This may be the opposite. Securities traded as cryptocurrencies on a publically auditable ledger will prevent all of the inflated paper that presently occurs on wallstreet stock exchanges.

Theoretically a company issues shares, and you buy one of those shares and then yoi own that share.

In practice, this hasn't been the case for many decades. As soon as securities holding houses became the standard way for stocks to trade hands, and they moved blocks from one house to another, they tended toward a credit ledger system between brokerages. This left the door open for settlememt nightmares, and it became typical to "balance the books" with ledger entries even when the total record of ownership of stock exceeded the total issued stock.

In other words, the holding houses are running fractional reserve of public exchange securities. Its been a well-known, longstanding and "unsolved" yet widely ignored problem on wallstreet all this time.

I hate to say it, but this may be an actual valid use-case for a shitcoin blockchain because of the verifiable public ledger. The problem is there is no incentive to hash-mine this coin, so it likely will settle on a proof-of-stake system.
