This is so funny. Every time they are given what they want the infrastructure crumbles to the point of being dangerous, and then the bears come to finish them off. Just ordinary bears are deadly enough for libertarians to LARP a Jurassic Park speedrun.
I guarantee that if there is a libertarian space colony, all of their life support systems will be contaminated by mutant tardigrades (aka water bears). The libertarians yearn for destruction by bears.
I did predict the twist, when they mentioned a completely safe quarantine zone. Nothing ever goes perfectly well with stories built on apocalyptic premises. But reading it still gave me chills. Excellent delivery.
