The "correct compensation" IMO is simply a negotiated fee for the temporary rent of the home office, negotiating if the worker just provide walls or a complete office ready to work. If he/she provide just the walls it's up to the employer provide and get back the rest. If it's already fully operational it's up to the employee keep it up and running. For the IT part, it's up to the company IT choosing a fully managed or partially managed setup, case by case. This might sound complex and long, but it's the way to avoid problems on both sides and a way to mitigate on both sides the "quick&easy" change that allow employers to drop employees as objects, and employees to treat employers like stakeholders in a consulting setup witch is by far the main friction point in full remote work.
