The point of a foundation, is that they actually have access and rules for joining, other than paying for ad-space and filling the foundations pockets for doing nothing.
That's centralization and/or regulation.
I don't think anyone is calling out for Centralization and regulation but I do think the community is looking for openness and transparency (and isn't that the basic premise of bilcoin). If that requires an external body and maybe this is the foundation or maybe it is NewCo an (independent community elected team) but I think this can be accomplished very easily through self disclosure. This may not even need to be a body or group and simply the community migration to exchanges that are open.
Centralization and regulation are not bad words just like needle and surgery are not bad when your system needs them urgently
anyone that talk with an idealized view of bitcoin has not lost tons of money in the space, via Mt Gox, hacking, scams, or any other way, the simple fact is the space it far too dangerous to operate in any reasonably ordinary way.
I'm not just calling for what you have provided for in the OP but also improvements to the btc protocol so security is written in; also for exchanges to be certified by community organizations, and for exchanges to be far more responsive to customer needs.
The space is too small for pervasive nonsense it's time for responsible players to emerge, be recognized, and duplicated.
