As I pointed out previously there is an unsupportable leap being made here b=
etween a vault (money warehouse) and any company (including a bank).
A company cannot possibly show that it has all of the money that every perso=
n has invested into it. At times a solvent company may even have zero cash. I=
t is also not possible for a company provide cryptographic proof of its many=
necessarily non-crypto assets and liabilities. What is presumed here is a c=
ommunity-verified sort of crypto balance sheet, with no considerations of ri=
sk - a central aspect of business.
As I said, if you want a vault, you can just use your own wallet. Solvency d=
oes not in any way imply 100% cash balance of the amounts invested. Raising m=
oney under such terms is pointless for both company and investors (the owner=
s of the company).

Banks (lending institutions) do not operate under any such pretense. US bank=
s require 7 day time deposits for all interest bearing accounts (read your d=
epositor agreement), and it should be clear that your uninsured balance is a=
t risk. Banks are investment funds, not money warehouses (in Rothbard=E2=80=99=
s terminology).
With a 100% of investment cash hoard, there is zero lending and zero return.=
This is true for all business.

=E2=80=9Crelate to=E2=80=9D is a far cry from 100% =E2=80=9Creserve=E2=80=9D=
. At 100% reserve an investment fund would most certainly fail. At 20% it wo=
uld fail. Money markets (banks without a reserve requirement) don=E2=80=99t b=
reak the buck, compete effectively with banks with reserve requirements (req=
uired by the taxpayer who is insuring deposits and providing discount credit=
), and maintain around 10% reserve. This is consistent with a world of peopl=
