This requires price stability, which is at odds with the use of crypto as a speculative investment vehicle. People use fiat to transact because it is stable. It’s stable because a central bank is using tools available to bring about stability.

There's another likely scenario (at least in my mind) where Bitcoin is a global reserve "currency" like gold used to be. In this instance, the on/off ramps that exist already would still likely be the ones around. That is to say, completely centralized instiutions that interface with completely centralized fiat currencies. Bitcoin isn't going to replace countries, countries will likely have fiat stablecoins which is exactly where our increasingly cashless societies are headed towards.

tldr; either the crypto itself is traded like real money, or a l2 or even centralized unconnected layer is - either way on/off ramps that currently exist (p2p and centralized) continue to exist and thrive.

You still need an on-ramp inside of the authoritarian country you want to depart

I've used crypto for regular monetary transactions (selling art) and it's a huge pain in the ass compared to using actual currency. The idea that people are going to do day-to-day purchases with bitcoin is pure fantasy, it would be a huge step back from what most people are used to.

You pay fees for every single transaction: chain storage, gas, if you want to deposit or withdraw or exchange to another currency, etc; it's slow to go through and at peak times you get gassed out and it doesn't go through at all.

The value fluctuates wildly at all times of day, so your transaction might lose a significant percent of value before you've had a chance to even access it let alone trade it for a more stable currency or asset. Oh, and you have zero safety net for if something is entered wrong, a key is lost, if you end up not receiving the item you purchased, you're outta luck and there's no bank or credit card agency you can petition for a chargeback. Plus you lose ALL your money with no recourse if you can't keep track of a non human memorizable secret key, or if it gets in any way intercepted or stolen from your computer, or if you accept the wrong transaction...

How can everyone convert bolivars into bitcoin? That would imply that equal amounts of bitcoin are being sold by someone in exchange for bolivar. Who is that and why do they think it's a good deal?

Ok then you tie an identity to a Bitcoin address and you have the same exact problem
