No, using it as a reminder that saying a high percentage of people have mild cases isn't a valid argument for saying we should just write off everyone else. Long COVID isn't as bad as Polio but that doesn't mean that it hasn't caused problems for millions of people or that we should be cavalier about assuming no long-term or worse problems will emerge. Getting people vaccinated before we relax restrictions is a cheap, easy, and highly effective way to reduce those risks.
