If you really need it to be secure and private, and are communicating mostly with known acquaintances within a reasonable radius, with low bandwidth requirements, LoRA with encryption is the best bet.
It is a higher bar of entry but at least you can be confident your messages won't be intercepted in any useful form.
Lots of things about US democracy are vaporware. The two-party paradigm and candidate selection in particular are a joke. Repubs various state party orgs eliminated any real primary challenge to Trump. Democrats spiked any meaningful primary challenges to Biden and then installed a replacement who received zero primary votes.
Then we get to "choose" between these arbitrary figures who were selected by elites and nobody really likes.
