Well, if a court makes you liable for some payment and you have eth assets, they will force you to liquidate and pay. They can't confiscate it but if you refuse you go to jail.
Ah, the old encryption vs. monkey wrench scenario. Never forget the monkey wrench.
This is critical: clever math is not going to protect your assets from the organization that has a monopoly on violence.
It's not a monopoly that's important here, just willingness and ability. Jimmy-the-Stereotype is but one entrant in the free market of violence but he can still force you to liquidate your assets unless you have a grudge against your own kneecaps.
You can hire Johnny-the-Mobster to protect you from Jimmy-the-Stereotype, but not against Uncle Sam or Grandpa Vladimir. State actors still have a disproportionate power.
Sure but Johnny-the-Mobster isn't exactly clever math either.
The term "monopoly on violence" refers specifically to legitimate violence.
