Constructive Devil's Advocacy:
So does this mean that if I really want to play a serial rapist with an immunity to jail time who uses his powers to justify uncomfortable sexual situations, that I can drag all of my Shang friends with me? Can we play a cadre of Furry BDSM experts who don't partake in plot due to what we, OOCly, really want out of the game is to have a new theme space where we can work our kink into roleplay on a new server?
The problem I see with promoting a liberal-Yes First arena of roleplay, is that NO will become, at some point, necessary to keep the game balanced and/or in genre. Some items on your list, like automated xp spends and build requests, sound like good ideas, but what if people start to buy things with XP with no justification (I was a 7-11 clerk with no combat skills yesterday, but I saved up xp and became a secret agent with diplomatic immunity after my last Thursday shift) or building egregious sex clubs on grid that would fit NO existing ordinance code ever (Undocumented Korean Immigrant K-Pop rape club SLASH torture hotel that is protected by the mayor of the city!)
If there's one thing I've learned from years of mushing is this: You have reasonable players, and then you have WHAT THE FUCK.
EXAMPLE: On Battlestar Genesis, I believe, we had a char named Gars. Gars' PB was Linc from Tropic Thunder (Robert Downey Jr playing Kirk Lazarus who was playing Lincoln, an "Amos and Andrew" talking Mississippi black man from 1967 who was in the Vietnam war). The problem was, he wanted to play the character, but saw nothing thematically wrong with being a marine who, mid-firefight, would say things like "Come get some, n+gga! Huah! Mississippi Black Snake in your MOUTH, Bitch!" in a setting that took tens of thousands of years before Earth history, in outer space, where there was no Vietnam war, nor Mississippi.
