Your argument is circular. Lending, borrowing, human coordination, liquidity management, censorship resistance, art patronage, royalties, permissionless non-custodial 24/7 trading, community development, a global pool of start up capital that rivals silicon valley and will eventually eclipse it, transparent treasury management across jurisdictions, user ownership, etc.
There's no need to believe crypto has value. It has value. It trades 24/7 with a market cap approaching $3 trillion. The market isn't wrong about what has value, the market determines what has value. Deny that all you want, but it's not going anywhere, it will only evolve and grow from here. We've barely explored the design space for what is possible.
