when you realise that people prefer choices and freedoms then you will understand that bitcoin gives an extra choice.
bitcoin is actually far different than what fiat is, in many many ways. bitcoin also offers abilities and strengths that gold cannot offer. it offers many abilities that paypal, mastercard, western union, bank accounts, bank notes cannot offer. and im not even talking about anonymity.
In theory yes Bitcoin offers autonomy.
The problem is it all breaks down at the choke point of the miners. Unfortunately.
But! To actually regulate the miners requires global cooperation of governments! So Bitcoin will force governments to accede to a global authority.
So yes, Bitcoin is unique and will have a role to play. But it will not achieve the outcome of the idealist delusion.
It will remain more of a speculation than a paradigm shift for transactions or decentralized finance, because for example to get fast transactions will require off chain, but off chain doesn't scale with Metcalf's Law, i.e. network effects are not the square of the number of users. Off chain fragments the userspace. Btw, this is a math argument, so make sure any rebuttal grasps that.
But Bitcoin is showing the way for an altcoin to provide what Bitcoin doesn't. This is the black swan possibility.
lastly if anyone is shouting that bitcoin is dead and will only be worth 1cent soon. how about you sell me 1bitcoin for 1c now and put your money where your mouth is. i dare you to sell me 1000 bitcoins for $10. until you are willing to do such a thing, your points are meaningless
I did not agree with that point of the OP. So I do not disagree with you on that point.
