I agree that crypto doesn't have a solid financial system backing it and that is necessary to be a replacement for the current one.
I'm not a huge crypto-believer, but I do think your criticism here is ultimately not really a criticism of crypto itself, but the financial system around it. Plenty of real-world currency suffers from the same lack of solid financial system. For example, I imagine you would be hard-pressed to find the same guarantees from banks dealing with venezuelan bolivars.
That being said, I think the best use case for crypto is still not one where every single person runs their own wallet. Rather, most people would use depository institutions who could run settlement on the blockchain. The main contribution and innovation is removal of red tape that is typically incurred when one wants to become a depository institution (mainly obtuse technical interfaces, slow clearing houses, etc).
Perhaps you primarily heard relatively uninformed people. "circumvent the current financial system" would probably be called some out of touch with reality woo-woo by many.
Many would instead say decentralization is the primary selling point.
Specifically, the inability of a small group to affect monetary policy, particularly the inflation rate, or to prevent access to the system.
The only people who have reason to use Bitcoin (or have ever used it) are individuals wanting uncensorable transactions. Bitcoin isn't intended to be used for carrying your life savings around on your smartphone. It's a fast, cheap and secure way to send money over long distances.
Edited to convey my message in a clearer manner.
How can this be if every transaction is in a public ledger?
The bank cares and takes quick action because they are liable for fraud in most cases. In other situations, like compromised PIN transactions or ACH fraud, their level of attention is very low.
Still super early days and there are some services that are starting to offer some services for custody or key storage in case safe keeping like Casa and whatnot. Just give it time. There are positive knock on effects to reducing credit fraud and charge backs.
