Sleeping with the Girls

[HoagieOfDoom]

It was not made to be "simpler" it is instead designed as "less prone to abuse"
Having that much physical strength would turn him into an outside context problem for baseline-earth if he was returned with it.
Unstated was the idea that the suit is also much easier to take away before they send him home.

My guess is Washuu's put some kind of remote kill-switch in the suit. We know that she loses his signal when he returns to baseline Earth, so I imagine that whenever she loses the signal the suit is deactivated. Instant prevention of power-abuse.
