"any computer can validate bcash" This is simply untrue and I have tested it myself with my own hardware. I don't know what talking points you think I'm "spouting" by my opinions are based on 10 years of study of the protocol. I have had these opinions, as I said, since long before the blocksize debate.
Also worth noting when you say "the original design" it was satoshi in 2010 who created the 1MB block size limit. I know this because I've read the code.
