the first step would be for people to stop minting new layer 2 tokens when we have enough already.
weeding out a bunch.
community pressure to stop supporting "bad apples" (projects)

rally around 1 or 2 layer 2 tokens.

more users always helps but without cleaning up the community.
they will not help.

That is how i would start.
Which is why darkcloaks.io only uses HBD plus LEO as a community token.

i have always maintained, the cream will always rise.

it's part of free markets and i dont know if we want to take away that feeling of 'if you wanna build something, you should'. entrepreneurial spirit is a great thing.

but like you said, most are dead projects with not a lot going for it. which is a curse for sure.
