It does take time and active effort to become fully productive in a remote environment. It's not something you're just born knowing how to do, it's a set of skills just like working in an office is a set of skills. You have to learn them.
The always entertaining saveitforparts Youtuber tried to make a "very small array" from a bunch of used satellite mini-dishes. He ran into all sorts of fun issues with his ad hoc construction.
I admire the guy for having as much fun with his failures as his successes.
But I have worked for a previous manager again. He left the original company too, but set up contracting as an outside consultant to the software we built. He'd hire me to do some of the work as needed. Great gig for him, not bad for me.
That's not that rare of a setup if you're working on large B2B software packages.
