"Why doesn't Farcaster have $0 sign ups"

Why doesn't Etheruem have $0 gas fees?

I’d ignore the q

but can also do a simple to get  explanation

exploring new frontiers in tech, ai, states, farcaster DAU since 2023, product background

or are you going to get into legal troubles if you start marketing farcaster as something, using which, you earn crypto, can send money to anyone out here etc.

or needs to be clear what they’re missing on here 

bet most people hearing about farcaster have no idea what’s happening here and why they should sign up, not to mention paying for it
