How can a group of volunteers build at least the tech for a replacement for the internet?

I was hoping that each individual user could run and maintain a piece of the infrastructure in a decentralized grassroots way.

How can users build a community owned and maintained replacement for the internet?

I hope that we can have our own servers and mesh/line/tower infrastructure and like wikipedia/internet-archive type organization and user donations based funding.

How could this be realized?

Can this be done with a custom made router that has a stronger wifi that can mesh with other’s of it’s kind? like a city wide mesh? or what are ways to do this?

Edit: this is not meant as a second dark web but more like geocities or the old internet with usermade websites

    I also don’t see how hobbyists can install undersea cables.

      More practical for hobbyists to launch satellites. Which some have. There are amateur radio satellites in orbit.

        UHF is strictly line of sight, and finicky HF (which bounces off the ionosphere) might have a total global bandwidth of 15mbit/s during a good hour of a good day. For everyone. If you use the entire possible spectrum.

          It’s kinda funny, the 2 meter amateur radio band (in the United States this is 144 to 148 MHz, right in the middle of VHF) is 4 MHz wide. If you add up ALL of the available bandwidth allocated to amateurs from 10 meters down, it adds up to less than 4 MHz. The 70cm band is tens of MHz wide.
