That would work. But it’s a terrifying worldview that citizens should be vassals to the state instead of the other way around.
Capital flight is a form of class warfare. Controls against it are the majority, workers who don’t own capital, enforcing a social contract against those who do.
Of course, that will only happen in states where workers are in power. In most countries that isn’t the case and, unsurprisingly, there are weak capital flight controls.
Voluntary association and participation of individuals should be a baseline understanding.
Individuals associating voluntarily is a liberal fiction. Such freedom only exists if you are already wealthy. Otherwise you have to work for an owner of capital or starve.
I don't think being hungry negates voluntary association.
Being hungry should not compel another to association any more than being horny should.
Is that voluntary association? Seems to me like the owners of capital exploit the labour of workers, because they have the ability to compel it.
Now you want to sleep.. need I continue?
In short, the violence is not in "letting someone starve". Most people aren't out there trying to starve themselves. The violence is in preventing someone from saving themselves. Being homeless/penniless is an eyesore for those that aren't. The actions taken to fix the eyesore are the source of violence. What happens to a panhandler if they refuse to comply with police's arbitrarily justified order to "relocate"?
The laws (and even the liberal ideology you adhere to) exist to favour the ruling class. Why would the ruling class do anything else? When the ruling class are the owners of capital, the laws and culture disfavour workers.
Ultimately it’s not worth discussing this to death yet again, it has been done countless times in the last couple hundred years.
The only real violence you mentioned is if police attack striking workers, which is exceedingly rare in most developed countries with the rule of law. What percentage of striking workers do you think are physically harmed by police in the us? If you think that is a likely or common outcome, we are probably living in different realities. You say that laws just favor the workers, but I wouldn't want to be a worker in a society without property rights. There is no point in working if any value you create can be stolen with impunity.
Maybe you wouldn’t want to move to a country where the working class is in charge, as opposed to your own class. I don’t dispute that.
In fact, in two of the countries that presently have significant capital controls (China and Russia), even your human capital is controlled with internal passports that limit where in your own country you can move to.
Of course, I likewise don't dispute that I don't know what your preferences are. My original statement ("you likely wouldn't want to") was intended to be a general statement, not for you in particular as an individual.
