I'm not sure I get your objection: Physical cash is exactly the use case for bitcoin.

There will be financial services and other layers built on top of bitcoin, just as it is done for the dollar, and we are seeing the nascent industry now. (Whoever provides insured services first is going to make a mint.)

I thought Bitcoin was more a store of value (e.g. analogous to gold) than a currency similar to physical cash?

If so the problem becomes, is your personal security up to defending attackers who want to take your pile of digital gold.

Physical cash is money, and serves the functions of money (see eg https://en.wikipedia.org/wiki/Money#Functions)

Bitcoin does the same.

In the nascent crypto world, different areas are using this new money in different ways: The US currently tends to store of value. Other areas (Venezuela, El Salvador) are tending toward medium of exchange.

In any case: OP's reversibility-of-transactions is a financial services function, not a "money" function.
