I want to discuss the vision of bitcoin future. One of the main idea of Bitcoin was decentralization, but now we can see that all hashrate is concentrated in pools, which works under some jurisdiction, pay taxes, burn electricity - they are legal.
Pools don't burn electricity the way you think, and pools are not owning the hash rate, in most cases it's miners that point their gear to a pool...which brings us to the flaw in your scenario...Pools do not burn electricity. They create transactions using hash rate of miners. So it will be fair to say that they indirectly owning the hash rate.
Lets imagine that pools have some blacklist of addresses for which they do not process transactions.
At which point miners will be against this censorship which will, of course, hurt bitcoin and their profits and they will point their gear towards a pool that does not havea blacklist, easy as pie.The lists will be very small against full transactions bandwidth. Therefore, using blacklists will not affect the income of miners.
From the other side the first thing that miners care of is their profit. If pool gives good fees miners will go to this pool, no matter if it is controlled by somebody or not.
As pools control almost all hashrate there will not be any real chance to find block outside the pool.
As I said, pools don't control the hash rate, so, come with another scenario next time.Read above. Small miners can do noting with their hash rate without pools.
The only way to regulate it is to regulate miners. As for miners, they will have to concentrate in pools, because is no another way to find a block in acceptable time. The pools will work in some jurisdiction under it's laws. So they will have to do what they will be said by laws of this jurisdiction.
p2pool, problem solved
Maybe. But I heard that miners always care about internet connection speed and quality for fast block propagation. p2p is always slower than direct connections. But maybe one of ways.
