I used to write remote dashboards for autonomous vehicles, and if we had been able to fully support remote operation (latency was just unbearable at the time), we would have gladly done so, if only to unstuck vehicles from tricky situations.
Also, it seems like it's already done in other robotaxi setups.
It makes sense for the company, as long as the remote operator only drives a fraction of the miles ran by the vehicles (and if you can keep the wage low enough, while still ensuring driver engagement.)
It makes sense for the user as long as the vehicle reach its destination, and they don't have to car about driving.
I would still heavily fine Tesla for calling it "Full Self Driving" or "Autopilot", because it's a plain lie.
But Elon retired from science & engineering to focus on running an ad-funded political campaigning platform, so "truth / lies" is a bit of moot point.
