Nah I'm fine with the rule, even with the reasons you've stated, despite how I too have made a good deal of bells with turnips and lucking out with a friend.
This, in combination with tarantula island and taking advantage of Flick, can lead to a large amount of bells. Not only that but even if we've banned duping and things that look like offering of an exorbitant amount bells was made from duping crowns, those bells are lurking in the shadows of the overall economy of New Horizons. Yes, people could start selling Raymond or Audie for upwards of 10 million bells and you'd regularly have folks buying them for that much. That's what they're saving towards with the methods I mentioned above as well as the duping methods.
However, not everyone plays this game with the luck of having a friend that has amazing turnip prices and patience for you to take trips back and forth. Not everyone knows how to make any island tarantula island or maybe even has arachnophobia or something.
And so they are just accumulating bells naturally and with hard work in other ways and that's not going to make them as rich as many people already are. And yet if we force people to sell villagers like Raymond or Audie for less than three million they'll just sell them on reddit or elsewhere instead of here. And honestly? Yeah, that's fine, for now. However staff needs to gradually allow an increase down the road by the time it's mid May I'd say. But for now I understand why they stand where they do and think it's valid.

I mean I'm aaaalmost on the side of OP here but I think another reason why it's okay for it to take time is because it encourages time spent with villagers people have and I think that would have an interesting way of changing what the tiers will look like when villager trading gets booming again. It'll never be at the level it once was because of cards, but I think there will still be an economy involved with it.
