Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

And no, I'm not talking about pirating on the internet, I'm talking about getting your internet connection to the outside world without paying or having a subscription or license. Something like a mesh network with your neighbors with the exit node being one person's high-speed fiber line, or even an exit node through a free public wifi network that you've hidden a little repeater device within range of... something like that could be interesting. I've been thinking lately of a world where decentralized networks become more common, and where people can freely use the internet without paying an ISP. What are your thoughts?
