Since it requires everyone to be connected all the time for anything to get done, that's hardly a complete solution. At best it's a hack that partially solves the problem under some very specific circumstances, like having a robust network that allows the nodes to communicate and achieve consensus for each new block on the chain. If part of the network gets cut off from the rest they can't participate, they're instead left with an orphan blockchain that will eventually have to be reconciled, and all their changes will get rolled back. Far from ideal. BitTorrent, by way of example, is resilient even in situations where the network has been split or damaged. If you can connect to a single seed you're good. If you lose that seed, but you can find another, you're still good, you can pick up where your transfer left off. There's no single point of failure: There's multiple trackers, multiple seeds, multiple everything and if any part of this fails, the whole thing can muddle along in a degraded but still functional state. Please don't comment on things you don't understand.
