Internet access is not a 'right'.
In the US, a standard connection is for one residence. This is according to the Terms of Service you agree to with your ISP. If you want to do other, that would be a business connection.
You can't just 'share' your home connection between all your neighbors.
But....For that many people, a business connection would not be that much more per person/family.
So...you are creating a small business to distribute internet access among several households. Don't 'bypass' the ISP regs...work with them.
And yes, one or more teenagers will be bandwidth suckers. That is what teenagers do.
Additionally, if it all flows through your connection, any investigation into illegal operations will start with you.
Finally, WiFi over a 2 mile link from town will no longer be 'broadband' once you then deliver it to your customers.
