Where does Andreas state that BTC has a physical network connecting it's nodes? Andreas does not claim there is such a physical network. Neither he, nor you, have a dedicated satellite, radio, or wired connection between each other, exchanges, and miners, solely for BTC.

BTC has a software application that allows all those parties to communicate over the internet, which BTC doesn't own. Did you ever get a bill, or receive deed or title to any such physical property when you acquired BTC? You access BTC's software network of decentalized nodes as does everyone else - over the internet.
