Yes, there are a variety of methods that could work. It should be seriously studied to see what works best.
I hadn't thought about remote work and you're right. It's an excellent solution, at least for the jobs that don't require presence. I don't think politicians necessarily need to do much for remote work to be successful, as long as they don't block it. It is very attractive to employees, because commuting is terrible, and I have seen a lot of pressure in companies to allow remote working. Hopefully it will be more widely adopted in the future.

Seems to me remote working and the improvement of "cheaper" areas, organically (as more people spend money in these areas and increase demand for services there) is the most viable solution but something governments can't seem to grasp or choose not to grasp
