If I'm thinking right, this is similar to a minimum wage law but sort of in reverse. It would change from the current situation(no minimum wage) where every SPS owner who cares to rent out their SPS can get a renter(employer) but at a lower price, to a system where every SPS owner who wants to rent it out has to wait in line for a wanna be renter at the artificially higher price.
So instead of dirt cheap SPS rentals we would likely end up with a glut of SPS for rent with few people willing to rent it. But maybe with a slight increase to say the 0.002 or 0.003 option we might be able to thread the needle and find the sweet spot of plenty of rentors and plenty of rentees.
I would love it if the system changed to where people put up their SPS for rent and renters come rent it out, and then it auto undelegates after 7 days. Instead of the way it works now where you have to manually find a renter and manually undelegate.
