I'm totally on board with online classes to begin the school year. The caveat there is that there are MANY instructional and support positions in every district that should then be laid off and on unemployment.
No reason for taxpayers to pay for phys-ed teachers, athletic coaches (for those affected sports), school admin, food service staff, etc...
My 2nd grader's phys ed teacher still had activities and assignments for students at home.
It just requires some creativity for the activities... But you can definitely still do tutorial videos on techniques for various sports... Plus, physical education isn't just about playing in the gym. Especially for the older grades, phys ed also tends to cover topics such as health/nutrition, and could also touch on sports medicine topics (how to treat a sports injury, how to wrap an ankle, etc...). This situation can also be used to assess how things are currently being done and maybe start looking at new ways to teach phyiscal education... The education system as a whole (in my country and yours) are long overdue for a tune up anyways.
