Even if you could do that, the barriers are insane compared to cash and cards.

Just the security practices required to avoid fraud are absurd, but since scammers can irreversibly empty your wallet, they're required. There's no credit card company to call, no fraud detection, no withdrawal limits, no way to lock your stolen card.
