The person or company paying you gets to define what you’re being paid for. That’s the way it works. If you don’t like the definition because it includes showing up in person you have options, one of which is to find a job more to your liking. Another is to unionize and with like minded colleagues negotiate for what you want. Simply complaining isn’t going to move the needle at all. If you are important enough the rules will change for you. If not, that’s life, and no one said it would be exactly what you want it to be.
