In the US, you can buy prepaid sim cards with cash and without ID.

I know of a hackerspace where people go buy and activate prepaid sims then toss them in a communal bowl.

Take a sim leave a sim.

There are always ways around this nonsense.

But I believe these are scrutinized pretty heavily. I saw an article Woz wrote and you have to call someone before they are activated - I guess that might be a 6dof thing to identify your habits.
