You're using terms in non-standard ways. Putting money into a bank is not
considered "lending" to the bank. You may make a case that you're lending
to a bank, and that they legally owe you repayment of that money on demand
limited by the terms you mentioned. But regardless of a case that can be
made there, pretty much no one considers that "lending". Since you you like
defining things legally, depositing money in a bank is legally not defined
as lending to the bank.

So no, all other scenarios do not imply lending. You can have your coins in
custody with someone else, and that someone else can keep 100% reserves if
they choose (or agreed to) and can prove it to you via the method I
described or the methods others have linked to.

> They are time deposits, read your bank agreement.

You are not correct
<https://www.investopedia.com/terms/t/timedeposit.asp#:~:text=A%20time%20deposit%20is%20an,pre%2Dset%20date%20of%20maturity.&text=Time%20deposits%20generally%20pay%20a,of%20investment%20is%20term%20deposit.>.

if you don't believe me. The only way you would be correct is if banks were
committing fraud and calling something a "savings account" when it isn't in
fact a savings account.

> money markets have had no reserve requirement and have a nearly spotless
record of satisfying their obligations.

Lol, money markets are so new that they've had no opportunity to show their
true risk. In the finance world, things work fine for a long time until
they fail spectacularly, losing more than the gain they made in the first
place. This is a regular occurence. Its the reason bitcoin was created.

> Irrelevant.

It is certainly not irrelevant. People have been lead to believe that they
can withdraw their money from their accounts. People expect this. Banks are
doing nothing to educate people on the limitations of that fact. PoR would
give people the ability to see quite accurately how much reserves there are
and can use this knowledge to put pressure on institutions to keep the
reserves those people think they should keep.

> Without 100% “reserve” there is no way to cryptographically demonstrate
“solvency”.

You can show proof that you're 80% solvent, and then claim the other 20% is
in other assets. This is, again, still useful.

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

You're right, but that's irrelevant.

But it seems like you're not interested in understanding what I'm saying or
discussing these things honestly. So I'm going to end my conversation with
you here.
