You can prove that in your own wallet. All other scenarios imply lending (which is what is implied by “reserve”) and lending cannot be 100% reserve.

I am, as banks are lending institutions.

Up to the insured limit, in 7 days. This is of course true because the taxpayer has insured the bank to that level.

They are time deposits, read your bank agreement. Not that it makes any difference. How the contract is satisfied is not a term of the contract, just that it is. And as I pointed out, money markets have had no reserve requirement and have a nearly spotless record of satisfying their obligations.

Irrelevant.

See above.

Without 100% “reserve” there is no way to cryptographically demonstrate “solvency”. And even with that, investors would have to accept the promise that there are no other liabilities.

The schemes don’t preclude hacks, insider or otherwise, bankruptcy, or state seizure, no matter what the reserve.

It’s information, sure, but it’s not what people seem to think. If one wants full reserve banking, use a wallet. If one wants to invest, the money will be spent - that’s why it was raised. There can be no covenant placed on it that will ensure it’s return.
