OK right now I have a little trouble taking your position seriously because you have seriously misinterpreted the Constitution. The full quote that you were looking for would be: "Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
What that doesn't mean is freedom to gather with a bunch of friends where and whenever you want. What it does mean is the legal right to stage peaceful protests or gather in public (with reasonable restrictions).
If needed I can run over to the library and grab you a list of cases on that, but I think you'll have trouble finding any for "couchsurfing."
What distinguishes "peaceable assembly" from meeting with a bunch of your friends? Some of the most important assemblies were antislavery meetings in barns, where meeting in public might mean suicide - does it say "peaceably assemble in public"? The prohibition is against government interference in all "peaceable assemblies" which is to say, all peaceful meetings. There are limitations, of course (eg I generally can't assemble in the street), but what reasonable restrictions intrude into the home? You do your name-sake disservice.
