An important difference *might* be that law enforcement can take down some agencies, some independents, some brothels, some streetwalkers etc without depriving any mongers (including themselves) from access to p4p because each agency, Indie, brothel operates on its own, soother are always others left (unless it is an incredibly serious and effective crack down). However, taking SA down, that one company and website, would make SBs far less available in just that one action.
Also SA could afford to mount a serious legal defense (i.e., hire top level attorneys), unlike the individual SWs and small businesses that the authorities normally target.
Anyway, I guess we will see.
