I was also thinking the same, but they don't really need to enforce it proactively. By making it "illegal", they can just pick up people they don't like and force them to unlock it. If they don't - believe it or not, straight to jail. Basically what is happening now in many countries, but legal.
So, from what little research I did the robots cost from 5000$ to 500000$, as most articles point out the advanced robots cost 200000-300000$. In a lot of places around the world that's like paying a human for 8-10 years. Humans are easily "replaceable", where those robots have maintenance cost additional to the initial "investment". How is that feasible in the eyes of the big money oligarchs? I genuinely don't understand the end goal here.
