Any RF comms can be jammed, you will need ground to satellite laser communications to accomplish this (or you were close enough to a terrestrial free space optics ground station outside of nation state borders a satellite isn't required).

RF comms can't realistically be jammed across the entirety of a whole country, though, so this is definitely a case of "something is better than nothing", and it absolutely makes sense to establish community-level networking/comms at least.

Eh I don't think there are enough jammers to get everywhere. Otherwise a twinkling sea of laser light house to house repeaters, red stars in the dark is a pretty sounding dystopia.
