Right, what you have described requires a central authority to 1) manage access to the funds (instead of trusting the tipper not to spend the funds he gave the tippee), and 2) avoid blockchain overhead by spending from accounts directly. Double spending then is prevented by trust in the central authority in both cases. The only useful part of the crypto currency left is the account-less nature of it, which can be done off the blockchain (has to be really here per number 2).
It's a UX problem in the payments space, which is not really a problem crypto helps with is my point. Definitely see the problem, just don't see the crypto angle.
Well said, I agree with that, although I do think there is a difference between trusting a central authority to maintain an opaque system vs merely being a regulatory figure maintaining a transparent system. If that’s even possible :)
We are currently still trusting places like Coinbase as much as we would need to already, to implement this sort of system. Why? Because you’re right - it’s a current UX problem of payments, not something crypto inherently solves.
