I agree it might be a good result if the Omicron variant infects a lot of people. It might solve a lot of problems. However, I would not want to get it deliberately or have my family get it. what if you try to get omicron and then get one of the other variants instead and get really sick? What if you have long-term side effects? What if getting infected with Omicron does not protect you from future infections?
As for Chicken Pox. Those that got chicken pox like me (not on purpose) are more susceptible to Shingles later in life. I have known people who got it and suffered with it for months. Fortunately, there is now a vaccine.
I understand that herd immunity can sometimes be a good thing if a virus is mild, but I would never deliberately get myself or a family member sick. I'd rather not get sick. It doesn't mean shut everything down or withdraw from society, but I prefer taking some reasonable precautions.
