I think Bitcoin can increase the blocksize now,
Fine, then increase it. I'm all eyes, we see amazing 7% hashrate, the mainstream media are "under control", so why not do it?
This is the first real experiment in decentralized governance, it might fail, or the economic majority might even make the wrong choice. There are many factors that will determine the outcome of this existential crisis. If I could just increase the blocksize I would not be here attempting to convince my peers that it is the right thing to do, it is a process, one that we are all a part off.
