Currency barter means you end up piling up a basket of currencies.
And you will also have BTC in the basket.
Then the question is how to balance BTC together with other currencies. And the answer is just keep BTC, the rest are not needed as reserve.
And in case you set BTC aside, holding zero, You are not against BTC, you are against yourself! So expect others protect against you soon as you either have no currency (weak) or you want your own currency as the reserve (dominant).
We need global trade as we want to produce the best and consume the best and do it (multi-) planet scale.
Even if you argue for one type of currency, you argue for BTC. You still need to get a reserve which every one accepts, in exchange of your own currency (work).
The only option is BTC, as all transactions are immutable (final) and already funded by a one source. Otherwise you have no reserve and if there is a reserve, it is not yours!
There is a thing that you only have a "single shot",
I don't give that to AI.
Can you identify who custody BTC? You can not!
Therefore, surrender yourself. You save some time ahead of others.
Without XYZ submitting a self report, it is impossible to know which addresses is at XYZ's custody. Basically eliminating BTC altogether, while they just make it stronger if they do that.
Even if XYZ's counter party shares information regarding a BTC transaction with XYZ. It is not known the other side of the transaction was really XYZ or the counter party itself (or its loved/hated ones) who find a chance to distract authorities and throwing their own responsibilities at XYZ. It is probably a crime if they can not prove it! The only possible way is XYZ reporting all account addresses that "are at XYZ's custody".
Therefore, the only purpose of BTC taxes is to eliminate those who breach their own privacy.
Technology is code and code can be copied once given access to, no point of return! Therefore, BTC is the only way to secure payment for technology.
Without BTC, either technology doesn't form or just goes where money is printable! As that is the only one who can secure a payment for!
BTC protects you against AI.
And HGL/Z enables you to modify AI.
Hold BTC, Otherwise AI milks you!
The way out of BTC is HGL/Z. Ultimate privacy is impossible without ultimate integrity.
Don't lend the king's crown, without securing a return, first and foremost! You own a technology when you can replace functions for yourself and/or for others as soon as it breaks.
Otherwise you are going to trust to your counter party, to secure the king's crown for you!
The way out is to hold BTC, period.
