Vaccinated individuals can definitely catch and spread the virus, especially with Omicron, so any individual person may or may not catch and spread it whether they are vaccinated or not... that is a true statement. But at the group level, we can say that we'd see X% less severe cases, X% less hospitalizations, and X% less deaths if everyone was vaccinated vs nobody vaccinated... that is also a true statement.
So at the tail end of this he's right that we'll eventually reach an endemic state regardless of how many get vaxxed or boosted while the counter argument is that yes, you are right, but we can get there faster with less disease/death, mutations, and strain on the healthcare system if people just get the shot. IMO we're really talking about is the statistical benefit of everyone embracing a particular behavior and to what extend a behavior needs to statistically benefits society in order to justify us strongly enforcing or mandating it.
In the case of the vaccine there is not a lot of downside (for most of the population though the situation with young men IMO is not clear cut) and a good deal of upside which is why I think people should get them. However, I am much less supportive of punitive measures than many seem to be. You'd be shocked to see what people are willing to let the government do to their fellow citizens in the name of safety or "public health". Rasmussen just released a poll, and I really hate to post it because I don't want a partisan flame war to start over this, but large percentages of the population support digitally tracking unvaccinated people, confining them to their homes, putting them in facilities, and even removing their children...
