Yeah they're some really valid points - it does get really boring sitting in one spot at home. I try to move to a different spot in the house after each period and do exercise before or after school to keep my brain going. Good luck to you too and hope you're surviving lockdown ok.
I find online schooling much better. Obviously there are some people (probably the majority) that prefer physically being in class and being taught by a teacher. Despite this, I've always found online resources and videos immensely more engaging and educational than teachers.
