I get your overall point, but you're greatly exaggerating the length of time here. The entire pandemic has been going on for less than 2 years. I also don't know any district that wasn't in person this entire school year. Every family I know in my area (a pretty liberal area of the US) had a packed summer involving camps, friends, and road trips. Kids truly sat at home for about 1 year.
Now envision:
You are a parent who HAS to work to make ends meet. Your work has to be in person (nurse, meat packing plant etc). You have two kids 3 years apart, say 7 and 10. One you just were able to adjust to school after years of sensory and social issues. The school is closed. The kids cant go in but bars are open.
Certainly my circle is wealthier, but it is a major city and any mandates would apply city-wide. Rural areas have even fewer COVID restrictions. Please point me to a school district in the United States that has had no in-person option this school year.
I live in a large U.S. city. For this discussion I'll include the metropolitan area which has a total population of roughly 2.5 million. The schools closed in the Spring of 2020 - just as the disease was first spreading. In the Fall of 2020 they were partially open - kids would go to school 2-3 days per week. By Spring of 2021 they were completely back at school though there was a mask requirement. That's the state we've been in since. So in total we had 3-4 months of no in-person school. Certainly not the 3 years the commenter you're replying to has claimed - as you pointed out this pandemic hasn't even hit the two year mark yet!
It's been the norm for some time to have in-person classes. School districts make the headlines when they cancel in-person classes and even then that situation only lasts a couple of weeks. Look at the most recent case in Chicago - it lasted one week. Since I live across the street from a large park I can tell you the kids are in school, they're playing outside, they're doing after school activities, and they're playing sports. I don't know what these people are getting on about acting like kids have been locked in their homes for two years.
