But that's just an assumption. Many people seem to have pre-existing immunity. A study was done in which unvaccinated, non previously infected volunteers actually lay down in bed for a while with SARS-CoV-2 infected liquid in their noses (eww). So they were unequivocally exposed to a massive dose but only about half got COVID. There is no explanation for this within the bounds of the assumptions made by authorities.

In reality, even if you get Omicron now it's so mild it's unlikely to cause any more heart damage than any other common cold. The danger has passed. Except that, almost everyone decided to massively expose themselves to spike protein over and over. So if spikes cause heart damage and they do, especially when the vaccine gets into the bloodstream, then the vaccines will do more damage than the virus could ever do simply because nobody has pre-existing immunity to it.

Some level of pre-existing immunity due to prior exposure to other similar coronaviruses is possible but hasn't been confirmed.

Many patients who are exposed to SARS-CoV-2 quickly fight off the infection with an innate immune response before the adaptive immune response really engages. That can happen with no pre-existing immunity. Some people just have better immune systems.

Are you trying to define an immune system that can fight off SARS-CoV-2 without having seen it before is not "pre-existing immunity"? If so isn't that merely playing with words? You seem to be agreeing with what I'm saying but arguing that the terminology should be different.
