> Duplicating a painting has a huge overhead. Duplicates don't sell. This is very similar in crypto - if you duplicate an existing blockchain, its block space doesn't sell. Art - and blockchains - sell because they are original, liquid, come with durable social proof, and have resale prospects and/or utility (real or perceived). > Thousands of computers are doing the same thing, repeating the same calculations and therefore not improving capacity in any way. I think I get what you're saying - if a blockchain were able to run on a single computer, then gas would be very cheap because each calculation would only need to be run once. Current blockchain protocols, of course, do not work like that. So if I might try to paraphrase your argument about overhead, it boils down to "if blockchains did not work the way they do, then gas costs would be cheaper." Which I can't really argue with.
