If you're a customer, sure. But if you're a seller, it's about as handy for the basic "I need some form of web presence but don't wanna make and upkeep a website" use case, which facebook, instagram and twitter are increasingly failing at.
I don't see the problem with mastodon, people without accounts can't reply, but it can still be used as a message board. It's not much different from linking to a wordpress blog.
He is, but that's not what they see. What they see is the Ben Garrison body builder version of him. It's why his catchphrase was "winning", and everyone against him was a failing loser. I wouldn't be surprised if the whole election denial thing was just them (and honestly, him) not being able to cope with taking an L.
It does make sense, but if you start down that road, would the rest of the world be justified in seizing US assets to give to Sadam or the Taliban? After all, the invasion of Georgia practically copied the justification for bombing Yugoslavia. Or, where do you draw the line? Remember the last Venezuelan elections, when they declared the other guy the winner and handed him a bunch of gold that was a loan collateral?
But beyond that, the only reason there are any assets to seize is because it's understood they won't be seized. Anyone not part of the west is an idiot if they keep relying on anything that depends on being in the west's good graces. And anyone not an idiot will seek to decouple and construct fallbacks and alternatives, and then any leverage over them is lost.
The problem isn't "it's right/wrong to do this", it's "will doing this come back to bite me in the ass at a later date?"
More like, what's gonna stop the US from seizing Chinese assets? Or, rather, why would anyone trust the US with their assets if they can just be seized when your country becomes politically problematic? The core point is that the only reason the west has so many foreign assets and investments is because the rest of the world trusts them not to be seized and sold off. It would be less damaging long term to just print more money.
That's... a wild question, and would depend heavily on where the lines were, and what exactly "breaks up" means. But however it happens, if the dollar-based system is to go down, the only actors I see capable of taking it's place are China and maybe the EU. The only lever Russia has left in this regard is BRICS.
It's hilarious to me how every wonk in the US keeps warning everyone of Russian propaganda, and then unironically thinks Putin is powerful enough to fill a power vacum the size of the US of A.
"Ersatz" in English is basically adopted to mean "make-do replacement". A swamp cooler is an erzats air conditioner, for example.
