Is there any way one can connect independetly to the Internet?

They are doing some good things in New York City that might be aligned with Your question.

If You just want a rock solid reliable means of communication and privacy is not an issue, look into Morse Code on Amateur Radio or CW mode. I am 100% positive that if You managed to learn it and make contact with any HAM, they would happily forward your personal message for free.

if You are just looking for an untraceable connection, buy a SBC with cash from a local electronics store and find an open wifi connection. Just be sure to bin the SBC when You are done or learn about MAC spoofing at the very least.

If You are looking for a more permanent solution and are not overly concerned with the connection being traced back to Your geo location, but still want privacy. You could look into starting a numbered company then purchasing a StarLink system through it.

There may also be a few AmSats that offer connections but they would have extremely slow speeds.

It depends on what you mean by involvement and what you mean by commercial entity. You could probably connect through a co-op or non-profit or something similar if that qualifies as not a commercial entity, but they're almost certainly going to contract for transit through commercial entities.

The most independent way to connect IMHO, is to connect through a peering point/internet exchange, but you need to contract for physical space, for IP space, for connection to the peering point, and for connections with each other network you connect to there. So, you end up with lots of involvement, but you can also pick from many transit providers, and maybe peer directly with other networks (depending on their policies)

Edit to add: the thing about the internet is there is no 'the internet' to connect to, you're connecting (mostly transitively) to every other network (ideally), many of which are government or commercial networks.

How do you propose to do so? The internet is literally an inter-network of commercial and government network infrastructure. The entire fabric is commercial or governmental.

You can build your own local network, but the internet itself is a commercial operation which requires massive investments of time and energy to keep running. It's infrastructure, something best handled at scale.

Connecting to other continents requires fiber strung under the oceans, or a more bandwidth constrained path through satellites, or a very, very slow radio link (which must be government licensed)

Governments are very picky about entities that cross their borders.

You can use the Yggdrasil network, cjdns or one of the other similar projects. This allows you connect to the network and reach all the other nodes if you can find a way to peer (wired or radio) with another node.

To reach the traditional internet, you'll need someone else to provide a tunnel. But if your target also has a node in these networks you can communicate just fine.

It is not possible. Digital communication falls under national security for a country. You could do anything(within limits) within the bounds of a country, but all the digital communication that flows in and out of a country is built in such a way that the government can control it if required even if it is operated by private players.

The Internet is not a object like the ocean, or the sun etc. Internet itself is protocols. The 'wide web' itself is a collection of networked that agree to use the Internet Protocol to exchange information.

No, it's not possible no matter how much money you have. Communication networks in all nations are owned by their respective governments and some government mandated monopolies.
