Well a lot of people on this forum are founders or early employees in startups. Every dollar vcs set on fire chasing some obviously stupid idea, waste on crypto memecoins, etc is a dollar that is not helping some legitimate startup get funded.

Yes, but when you put it as "why are you investing in these bad ideas? Invest in mine, it's obviously much better", it sounds a lot more self-interested (and far more likely to be wrong).

You asked how it hurts people. That is how it hurts people.
