1) Studies show that vaccinated don't stop the spread of the variants but still slow it down compared to the not vaccinated. >In fact, it's possible that the currently vaccinated will be more susceptible to spread the new strains. On what is that assumption based? The vaccination effect is based on normal antibodies of the immune system, so there is no big difference between vaccinated and recovered.

2) You are confusing infection with infection disease. You can be sure you will get infected by the corona virus but that doesn't mean you'll get COVID. If 22,000,000 people get the corona virus if with low IFR like 0.003 you get 660 deaths and that's only for people under 30. Additionally you are ignoring the effect of the variants you are referencing in 1) Young people are more likely to get sick by the variants and herd immunity is based on antibodies and therefore have the same problem as he vaccine based antibodies. A new variant could make them equally useless.

3) We don't know the long term effects by corona either. In contrast to the vaccines, we have already found evidence of organ damage in the heart , lungs and kidneys with Corona, which may not disappear even in the long term.

The bottom line is that the risk without vaccination is much higher than with vaccination.
