I perfectly understand why people might be disappointed with Rainbow supporters, for multiple reasons. That's a perfectly valid opinion to have, but ultimately it is selfish - it does not relate to the overall state of the game and is limited to your own personal experience - especially since that experience will be limited to simply passing on these cards, not being locked out of the game by inaccessible deck prices or having your store lose revenue from worthless packs. We all want to live in a perfect world where all perspectives are equal and we can engage with the game however we want - but in the real world, I would prioritize having cards accessible and my Local Game Store not closing down/not quitting PTCG over optional collectible pieces having collectible-level prices.Mhmm. And then in the majority of what I said, I explained why others could possibly have issues with too many ultra rares. I gave my own personal take on it too, in order to make the explanation more relatable, giving the abridged version of how one gets to this conclusion.
Basically, everyone has different opinions. And whether intentional or not, you sounded like you were talking down on anyone who didn't like some of these cards.
Just to put it in other words - if we were to follow your needs exclusively (not saying you actually want that), then every pack in a box would be a Detective Pikachu pack.
