The need of not relying on a centralized entity or third parties in the digital space does exist.
EVERY transaction requires trust. I sell you a pair of shoes, you pay in bitcoin, oops! the box is actually full of cat poop, too bad, sucks to be you, you can't get your bitcoin back, shouldn't have trusted me.
Trust in the transaction system is not a dangerous component of commerce. Sure, you can trust Paypal to do the transaction for you (and also get benefits like chargebacks, disputes, and ID verification in return, not to mention the sub-second transaction speed), and what happens if they betray that trust? Well that's what governments are for, the two-ton hammer of the law will make sure you get your money back.
Not to mention, blockchain is the least trustworthy transaction system of the modern age. Over a billion dollars in crypto has been stolen out of people's accounts via exchange hacks and smart contract exploits in the last ten years. This has never happened to any US bank since the introduction of FDIC in 1933.
All in all it's all about the choice and preferences of individuals.
And why is that very minimal trust in the ability of your money to get from one account to another worth risking all your money by putting it in an account with a single point of failure with no recourse in the event of a breach?
In 88 years, no bank in the Untied States has ever lost a customer's money. To date, there are more bitcoin exchanges that have lost their users' money than there are that haven't.
I think it's clear that the concept of a wallet or account that can be created at any time in almost any place almost instantly, that can send and receive something of value securely is a valuable contribution.
As a developer I appreciate the ability to skip the use of a third party, I just wish there were more users in this network, but the network grows.
And this is not about the united states in particular. I'm not from the US, I'm glad if you didn't had any problems with your monetary system and banks, and I hope it continues for the good of everyone.
