Shorting the market is a terrible idea if you want people to take you seriously. „Of course Ed Zitron is speaking against the datacenter build-out, he has financial interests that the whole thing collapses,“ people would say.
Aside: I also fundamentally disagree with you, I think shorting is never a good idea, nor is participating any type of market game a good idea. These market games are a rigged game where the owners of capital engage in systematic exploitation of the working classes. Everyone who makes money by gaming the market made it because hundreds of worker did not get their fair share for their work.
