Yes. For certain definitions of "less hard" - he probably would work the same time, but he would have less new projects, less new investments, etc. - some companies that we know now would not exist, because there would be nobody having that kind of money laying around to be spent on crazy projects. Coinbase would probably not exist, because people who were crazy enough to spend money on that kind of extremely risky investments would not have that money around. It's not that those people would be poor - no, they probably would still have nice mansions from those $100M they were allowed to keep. But they wouldn't have enough money "they don't need" to throw them around on highly risky and completely insane projects like making a platform that trades "currency" which relies on bunch of computers repeatedly running hash functions.
