Not everyone in Tesla (or at any other automotive company) produces cars in a factory. Some write software, some write specifications, some do SIL/HIL testing, some do procurement, some work on legal concerns. A lot of these jobs can be done from home - maybe 50% of the company size (and I know from references from Daimler where I formerely worked that those things are still done in a WFH style). It seems like Elon wants nobody to work from home, independent of whether it would be possible or not. At the same time there's even some things in MAGMA companies that can not be done from home. If one is working in a datacenter to fix hosts which broke down, then it's simply not possible to the same from home.
