Amateur radio is not that hobby. There are significant restrictions on what it can be used for. And providing uncensored communication for others is not allowed.

Amateur radio is not for public use like public park. It is like a public golf course, where have to pay for membership and can only use it for certain things.

Also, amateur radio does not have that much spectrum for the bandwidths we expect for internet. That is what has kept the spectrum from being taken away. Much of the high frequenecy spectrum does have is shared with ISM bands.
