There were no economic sanctions imposed between East and West Germany; but making a contract with someone on the other side of the wall was still impractical, due to lack of diplomatic relations. Smart contracts solve that problem.
Other angles on this: the regular financial system in the Western world doesn’t let anyone transfer fiat currency to countries like Nigeria “for your protection”, even if you’re literally trying to run payroll for the registered employees of your Nigerian subsidiary company. (In other words, a de-facto trade embargo, but not a legal one, and not one to do with a any war.)
The only good way to do that payroll at this point is to send them crypto.
The flaw is that a transaction isn't positive-sum just because you and your trade partner are both happy. Your transaction may well incur negative externalities that outweigh the total profit enjoyed by you and your partner. For example, the world is much worse off if you sell a button-that-destroys-America to North Korea, even though you and North Korea are both pleased at the arrangement.
I don't want to put activity out of the reach of governments. Governments are the organ by which we decide what is and isn't acceptable behavior. If our governments are behaving unreasonably, the solution is to fix them, not to pursue anarchy.
I am surprised at the political ideas on display in this thread. This isn’t even under the comment in which I described the influence of “techno-libertarian anarcho-capitalism” on the crypto community! If you are not part of a western democracy, of course you do not have to care, but if you are, then you should. (Moreover if you think war is bad, like that other commenter agreed before wondering how to erase the effect of sanction deterrents, you should also care.)
Sure I do, however I also get to choose who I care about, and it definitely doesn't include people who make policies which are extraterritorially enforced on me.
>If you are not part of a western democracy, of course you do not have to care
What do you do when a "Western" "democracy" enforces their laws on you and all remaining solutions point you to services that are beholden to a "Western" "democracy".
Correct the aberrant behavior that caused your nation to get kicked out of the global trade system, or move to a nation that hasn't gone rogue. That's what the sanctions are meant to encourage. Bypassing the sanctions with clever math is just going to get the clever math outlawed; exerting international pressure to keep countries in line is far more important than your coinbase account.
Edit to add: avoid phrases like "the West", it's very "Us and Them", it's much better to be explicit: is this about NATO? The US and its closest allies? The EU?
And the reason why the USistan should entangle itself in that mess is ... what exactly?
The Budapest Memorandum on Security Assurances refers to three identical political agreements signed at the OSCE conference in Budapest, Hungary on 5 December 1994 to provide security assurances by its signatories relating to the accession of Belarus, Kazakhstan and Ukraine to the Treaty on the Non-Proliferation of Nuclear Weapons.
As a result, between 1994 and 1996, Belarus, Kazakhstan and Ukraine gave up their nuclear weapons. Until then, Ukraine had the world's third-largest nuclear weapons stockpile
If the US convinced Ukraine to give up their nuclear weapons with the promise they would help fend off an invasion, and then proceeds to not help fend off an invasion, what do you think happens the next time the US asks a country to give up their nukes?[EDIT]: Whatever happens to nukes that are "given up on". That's a lot of fissile material.
