There are still HR and legal overhead costs involved if you have human operators.
I think part of the answer is also that the space of things low-wage workers can physically do remotely via teleoperation isn’t that much larger than the space of things that can be fully automated but still much smaller than the space of things a local human can do. It’s a fairly narrow band to exploit, IMO, and the labor cost arbitrage spread is rarely worth the complexity of the extra logistics, capital investment, and maintenance.
