Because even my perception that you exist and that the game is actually happening is an assumption. I've had dreams where they seemed real and people seemed real within it, but weren't.
In your analogy, you both DO assume that you're actually watching an actual game that is both objectively happening and is not a fraudelent video (which given the technology we perceive to exist is possible).
I won't lie, it is sort of dumbfounding, but inescapable nonetheless. People don't tend to brim
ng up these assumptions in everday talk, which is why that scenario would probably never happen.
