Imagine a scenario where you park outside someones house and they have software on their router that allows you to send it bitcoins and access the internet using their connection, or even sitting at a cafe you send the p2p isp a coin and youre surfing.
No bank account needed and anyone can sit somewhere earning bitcoins all day just for sharing their wifi with people. I had this idea while sitting at a cafe in the city and they wanted me to register a credit card and give personal details to access a wifi point. Of course I avoided that like the plague
No one uses wifi anymore. Everyone has 4g.
And lots of people (like myself) only pay for the bare minimum of data (200MB/month), making wifi rather valuable.
