The biggest false dichotomy in crypto is this:
we should be building real apps instead of shitcoins!
This implies that you have a choice.
That you must either do one thing OR the other.
This is false — you do not have a choice.
People launching too many shitcoins is not the problem (and it is not something you control).
Our not building real apps that people want is the problem (and it is something you control).
If you're angry at degenerates launching shitcoins — you can get even by making useful apps that people want.
Nothing is stopping you from this. No one is "diluting" attention, you just haven’t created something worth paying attention to.
The only real issue here is getting mad at the market (and the human condition) instead of yourself for failing to build something people want.
