Yeah so let me tell why there’s a problem with that last part.
When the assumption is “this person will leave if we don’t resolve his block”, then it becomes a de facto method of running roughshod over that person.
You might say, “well that’s fine, that person made their position clear.” Well, no, they didn’t. Putting up a block doesn’t indicate a single state; it indicates two potential states. One state is that the person would like to stop the community from doing something they see as ruinous, and they care enough to talk about it; the community really should consider that the block is well-intentioned and that the person wants to stay.
The other state could be that the person has had enough of this community and is making their final stand to see if anyone will listen to reason before they leave.
Neither state is a problem on their own. The problem is that you cannot know which position the person is taking when they issue their block.
If the community treats a block as saying “I will leave if this goes through”, then the community may take the easy (and ruinous) road of not trying to resolve the block and instead forcing that person out by going forward with consensus.
Forcing people out through a funky legalistic interpretation of what a block means, instead of trying to understand where that person is coming from, is a great way to detonate a nuclear bomb in the community that you won’t recover from for a long while.
This isn’t theoretical, by the way. This happened in 2018 (see the places i linked above).
Noisebridge owns the resources. Easy.
Yeah we have talked about that somewhat. To some degree we already do that; you can donate directly to a particular Guild’s fund (e.g. the laser cutter, the sewing room…)
Then you’ll also be experimenting with being a landlord…
“should” 
What problem does subleasing and ownership solve, though?
All I can see is more problems being injected into the social space, as property ownership creates a feeling of entitlement. And what might usually be petty disagreements blow up to knock-down-drag-out fights when there is actual material property at stake.
