There is one major requirement for remote work, it’s called deadlines. Give people a paycheck, some requirements, and deadlines and I promise you the work will find a way to get done. They can browse Facebook all they want.
These types of work have the added risk of unauthorized people, such as the employee’s kids or friends, snooping in on sensitive information.
That might be helped by the employer providing a dedicated computer for remote work, with screen-recording and facial recognition that locks the system if you’re not (the only person) in view.
Perhaps having always-on video and voice surveillance on that computer, and announcing that fact, would force employees to create a dedicated distraction-free work environment in their homes.
If you're requiring someone pay attention to a monitor you can do the same thing - for example put a square on the image and require the employee to click it. Obviously though, this requires someone to actually critically think about protocols for ensuring work is done to a standard.
If touching points is all that's required, then that's all that will get done. The neural nets of all employees will eventually become trained to touch the points and not do the actual work you desire.
In the case of a security guard the 'real' job is to catalogue all things 'out of place' and then react if necessary.

You might want to think about how this effects the housing market if this take off long term.

All homes - should - begin to have offices anyway as people realize that physically going in to work isn't necessary to be productive.
Laptops can go anywhere, and my living room is empty until ~4pm when my kids get home. I've been remote for going on 5 years now and routinely take my work laptop to the kitchen or living room (though I'll concede I need a quiet room for some calls/tasks that involve PII).
