Well, if part of being off-grid pressuposes the existance of a huge global and domestic grid to fund, manufacture, transport, and sell you things like internet service, routers, Netflix shows, computer games, televisions, laptops, all kinds of electric and digital appliances, solar cells, batteries, and so on, trucks, factories and cargo ships to transport them, mines extracting resources to make them, the associated with the above waste disposal, even cities and businesses built around all these to support the people making those and their families (plus your own work, paid in regular currency to afford the aforementioned), I'm not sure how "off-grid" it really is...
This "off grid" sure is not some Walden style affair. It just means "I buy and setup "renewable energy" units for my family's exclusive energy production and storage and have a self-owned shit disposal method, otherwise you couldn't tell mine from any other house in the area".
