Blockchain topics have become a proxy war for Keynes/Hayek poorly framed as a technical discussion. I think most people who are passionately against crypto hold that view for non-technical reasons and more related to monetary policy. Which is valid, but suckers like me used to think questions like yours were posted in good-faith. I'd answer questions such as upgrades to PoW/PoS, TX rate limitations, side-chains, multi-sig, etc. After enough down-votes for factual answers you realize it was never about the technology.
