If they get nothing of what they want in terms of concessions, are roundly scorned by everybody but the extreme far right/libertarian bubble media, and the ringleaders end up in jail whenever this shit does fizzle out, why would anybody replicate their failure? And even if they do, is having far-right domestic extremists blow their criminal wad on low-stakes bullshit all that bad, considering how much of a threat the FBI says they are and how much worse it could be? These people caught the country by surprise and are playing up their 15 minutes as much as they can, but the media will move on to something else, soon enough, as they always do, leaving them sitting in a building with nothing to do and nowhere to go. It's not hard for me to see why the feds might see that as a better option than choosing to play their game and feed into the delusion that spawned this in the first place.
