Theres a lot of money going about now. I dont know how many and what money sinks we have by now, but my suggestion would be that items that are naturaly ungainable should be sold to all players for a reasonably high price.
I mean even the placement of bedrock and mob spawners is legal now. And im pretty sure that there are a couple of people around who would pay well to get fire blocks for crafting chainmails, of even pay additional money to get a full chainmail set. And what about all those who want to make windows out of portal blocks? I think it would only add even more possibilites and awesomeness to gain access to additional blocks, in return of stabilyzing the economy
