The local hero (entrepreneur/person in charge) is able to assign data capacity in exchange for any tradable goods or money. So, if a neighbor gives permission to install repeating hardware on his private property, he can get a regular " X GB Data each month for free" in return. The local hero could also be a local institution, so every bought GB of data supports a local school or community center.
Overall that will enable a fair & sustainable ecosystem embedded to the local economy, indexed to whatever currency or exchange adapted to local conditions.
