That statement is just absurd in this context. Your premise of this being injustice is wrong, don't engange in shitty rent seeking behaviour and you don't get expropriated, don't murder people and you won't have your right of free movement removed (or in the U.S. case you right to life...). Secondly, your falling for the paradox of tolerance (https://en.m.wikipedia.org/wiki/Paradox_of_tolerance), being intolerant of nazism isn't a slippery slope towards nazism, just as being intolerant towards injustice isn't a slippery slope towards injustice. We're not talking about vigilante groups assasinating some CEO and their Family here, but almost litterally that:

> these guys committed some unlawful thing, then the prosecutors should seek justice in the name of the people.

Because hat's literally what's happening. Massive unethical and unlawful behaviour by these companies, and the population asks the government to step in and protect them. Be it in the form of a law or a persecutor for said law, makes little difference.

> I'm completely dumbfounded that in countries that pride themselves as being democracies, expropriation is allowed by the law.

That's rich from someone from a country with only two parties of which one just tried a coup... You still misunderstand what expropriation means in germany, you get the same compensation as you'd get from the 5th.

You seem to somehow complect democracy, which literally derives it's name from the greek words for "power" and "people" with libertarian neiliberalism, where profits are more important than people.

Fun fact, democracy is a form of government and orthogonal to the system of economy. Few democratic countries have capitalism written into their base-laws, so you could just as well have a post money star trek democracy.
