"Finally, there’s (E) that more vaccinations won’t change the path of the pandemic at this point, so why are we bothering, choices have consequences, the unvaccinated will get sick but the vaccinated will mostly be fine, so all we’ll be out are a few medical bills (which will effectively get socialized, because insurance can’t discriminate and if you don’t have insurance mostly the government pays). I don’t buy this, there are a bunch of immunocompromised people, even for vaccinated people getting Covid is worth avoiding, and in practice if there’s lots of Covid out there the result will be lots of lost living of life. "

I basically agree. Just because we can't help everyone doesn't mean that we shouldn't help as many people as we can.
