Early evidence is that the protection against transmission from the booster appears to be quite fleeting (weeks, not months), so the main reason to vaccinate is really to protect yourself.
People seem to forget much of the world still has no access to vaccines. Every person being vaccinated with natural immunity is someone without immunity missing that vaccine.

So is France and Canada.
I'm not sure what you're asking. Are you saying that antibodies last 90 days to 6 months? Firstly that's incorrect as antibodies seem to be detectable even after 8 months in the study I'm remembering, but more importantly your immune system is made up of many parts and antibodies are not the primary response to coronaviruses since the antibodies do fade rather quickly.
Instead the many other parts of our immune system are extremely long lived with other coronaviruses and there's no reason to expect they won't be extremely long lived with covid.
In fact the reason you see so many asymptomatic cases with covid is because of preexisting natural immunity to similar coronaviruses.
> If they incubate a new variant themselves are they willing to be held personally liable?
Are you suggesting if we had the tech (we don't) to trace down the exact host where a virus mutates into a recognizably different strain that host should be liable? I think you should really reflect on exactly that would mean and exactly how harmful that would be for society. You do realize every single person in the entire world will either die in the next couple of years or without a doubt be attacked by covid, right? That means you'd basically be putting up a lottery system to see who gets to lose for being "ground zero" for a new variant mutation. This would be completely pointless and would serve only to hurt people with zero chance of helping anyone.
keyword being if and meaningfully.
Anyway that fake recipient may still need top notch expensive care to stay alive if he doesn't get mild covid. Are you suggesting that he should pay in full for those care since you state it only harms the fake recipient ?
Also, it increasingly seems that a third dose significantly increases protection against omicron.
