The comment you're replying to said that most political speech has moved to a few platforms. I haven't forgotten that IP addresses exist, but what has that got to do with my comment?
Nobody is preventing you from putting your political musings in a newsletter distributed by carrier pigeon, or setting up a coöperative news telegraph wire, or your own broadsheet printing press.
You are just as free as ever to put HTML on a server and air-drop and spray paint your dotted-quad all over the physical world. You are equally free to get a bullhorn and stand in the desert and preach to the prairie dogs, should you be so inclined.
