I don't want to get too far into this either because it's entirely unimportant, I just think your overly pessimistic viewpoint is largely incorrect in many regards and is neither helpful or constructive. It bothers me to no end that you're complaining about good magic sets after we just came out of one of the low points of magic's design (BFZ-RIX). While there have been a number of mistakes over the last 15 months or so by WOTC, a lot of this seems to be caused by trying to power up sets in reaction to the abysmally weak sets of 2015-18. It's going to take a while for them to get things right again.
The Conspiracy sets are not really comparable to Commander Legends in terms of print run. Both conspiracy sets were released within a month of the launch of a big Standard set (Conspiracy's June 6, 2014 was only six weeks before M15's July 18, 2014 release, and Take the Crown's August 26, 2016 was only a month before Kaladesh's September 30, 2016 release). Commander legends was supposed to be released on November 6th, although it has been pushed back to November 20th thanks to Covid. Kalheim isn't supposed to release until February 5, 2021. Effectively, Legends has almost three months on shelves before it's supplanted by another product, unlike the Conspiracy sets which had almost no time before the next major release. Conspiracy also did not have collector boosters, which as we have seen with standard sets, tend to drastically reduce prices on everything. Almost every card from a non-masters set with a collector booster released in the last year is under $30, save for *Uro.
It's also important to remember that many of the expensive cards in the conspiracy products stayed fairly reasonable in price for years, and either declined in price naturally or were brought back into the reasonable price range by a single reprint. Expropriate didn't spike above $20 for almost 2 years after Conspiracy take the Crown was released, and is now back down to about $15 after a single reprint in the mystery booster. The trend is roughly the same for Selvala, Heart of the Wilds. As for Conspiracy 1, almost none of the new cards went above $40, Council's Judgment, a Legacy staple, spiked to $20 about two years ago, but has been brought down to $5 due to its Double Masters printing.
You may argue that the high initial pre-order price of the Lotus dispels any previous precedent in regards to price trends of cards in supplemental products, but might I remind you of Dack Fayden, who pre-ordered at $60, but dropped down to only about $20 following the set release. A reprint in Eternal Masters brought it as far down as $14.
The point is, if they reprint Lotus one time in the next two years, it won't go insane in price.
*Uro is a bit special since he is the only card of any real value in THB. People stopped doing mass box openings fairly quickly since it became the Uro lottery after about two weeks. Plus, Uro is a 4 of in tier decks in many formats and a card commander players need. I'd be willing to bet more Uros are needed than Lotuses. Commander legends has multiple cards which seem to be potential commander staples, and has reprints of other high-value cards.
This actually hasn't had as big of an effect on product as you might think. Ikoria was the best selling spring set of all time, despite a slump in sales of other product due to the Pandemic. The only product that seems to have been negatively affected in a big way is Jumpstart, and I've heard that this is only because of the weird way the packs are organized. In-store play might not be possible here in the U.S on the 20th, but I don't think a lack of draft is going to tank this product's sales given that there are cards like the Lotus in the set which *many commander players are going to want.
(I say many because a lot of CEDH people I've spoken to think the card is only ok, it's not useful in 4 color decks like Atraxa. Pleasantkenobi did a great video on the topic. Of my three decks, the only one I would even consider adding this to is Kruphix, I don't feel like spending the money there because it's not even one of my semi-competitive decks. Perhaps this is anecdotal evidence, but I think most of the hype around this card is due to the fact that it costs 0 mana and has "lotus" in the name, not because it is actually an auto include in every deck. Many decks will play it, but not to the same degree as Sol Ring or Mana Crypt).
While I understand your point of view on this issue, you are not entirely correct on many points. This is not the worst thing ever, I don't even think it's hurting the game in any meaningful way. Secret Lair Walking Dead is worse than the Lotus. The print run is going to be larger than the Conspiracy sets, and the time it has on shelves is two to three times as long.
There are so many bad things going on the world right now (my country might have an attempt at a Fascist Coup in about 4 days), this is small potatoes even in the Magic community.
