You are right. I somewhat thoughtlessly thought "lock in" did not imply some kind of nefarious motive. It probably does. 

But "not portable" does not do justice to my thoughts.

Anyway, I'm obscuring my own point. I just think trying to get to motive is tricky.

I also find myself in a weird position apologizing for every variation of self-custody [that offers unilateral exit in all but the worst case at least] because the alternative is much worse and the alternative dominates right now.
