Critiquing lockdown policy because you can’t live your “nomadic lifestyle” is selfish. Critiquing lockdown because there are better alternatives is not. You chose to frame your argument in the former.
My critique of lockdowns goes far beyond not being able to live a nomadic lifestyle. Notice how I said that life isn't the same no matter where I am. I could write a whole essay, talk about how all my friends are depressed, etc., but that's outside the scope of my comment.
