The "risk from getting an infection" includes many other side effects besides myocarditis, I would not evaluate the risks from an unvaccinated viral infection (which can cause 100 other things besides myocarditis) vs the risk from vaccination (or vaccination + viral infection, which the most likely long term outcome) on the myocarditis axis alone.
Yes that's fair, but the risk profile from the vaccine is also not just relegated to myocarditis, that's just what's been getting attention. It will probably be years before we have an accurate risk assessment of both infection and vaccines. Given the availability of vaccines, it still makes sense to be choosier if you're in a potentially vulnerable population, which is what the paper suggests.
