I don't think we disagree then. However I would point out that "game" has a lot of overloaded meanings. When I talk about game in this context I normally include the social contract as part of that term. It seem like you here use "game" in a way that excludes social contract. This was not obvious from previous context unfortunately :/A few things.
First, while you might view it as disobedience, it's still due to the social contract(and how you personally view it) and not the game itself. The DM's authority in that moment is because of the social contract in agreeing to play the game where he's the DM and you are the players. The game itself gives no such authority over the players. It can't.
Second, I would not feel disobedient in the slightest if I refused such a request. Having to stand or sit while saying a speech is a purely out of game element. My standing or sitting has not bearing on whether or not my PC is standing or sitting, and I control the actions of my PC, not the DM. The DM has no right to expect that I would stand up for a speech my character was giving, and no right to be upset at my refusal.
Lastly, the difference between the first and second above might be cultural. I know America tends to stress individuality and personal freedoms more than many other countries out there, so I imagine that the social contracts would be different.
And another thing - in some cases acting out what your character is doing can really enhance the experience. If you one day are asked by your GM to raise for a speech, I would recommend you to comply. Having that excuse for acting a bit more "silly" than normal can be gold! (of course unless there for instance are physical limitations that make this less convenient than I would normally imagine)
