Why should we get rid of physical addresses? It's not really relevant for letters anymore, but people still need to go to places. Deliveries of goods are a bigger thing than ever before. I can imagine that in the future a company doesn't need to have a physical address to be registered. But we already have that too, PO boxes and addresses where you can register your company without having an office here.
