When I say that people (or as you refer to them „private individuals”) using their economic means (and therefore resources and time of others that they hire) on misguided projects is a negative phenomenon, that’s a whole complete statement.
I don’t need to design any world changes to go with that. So your line of inquiry makes it seem like you’re fighting some phantoms or replicating debate strategies that you’ve observed. That’s unnecessary. The statement still holds up.
The only objection you can make is the silly one: actually it’s not up to me to decide what’s misguided, it’s up to those people who have the means. Or you can say doing useless crap is actually good which is not even a valid objection in my book.
