The network infrastructure that you use your phone, computer, and other connected devices on doesn’t just magically appear out of nowhere.
The internet has no inherent speed. It has no inherent “full experience.” Both are determined by the technological capability of available hardware and equipment at a particular moment. On the network side, those are provided and maintained by private companies. It costs lots of money to change out, upgrade, and service entire networks as large as the ones we have here in the States.
If you want free internet and communal sharing of internet speed, it’s called public WiFi.
