But then you're applying a bit of real life to Trek, and in real life inertial dampner failure won't just knock you out of your seat, it'll turn you into a thin paste on the turbolift door.
If it was a real window you'd need that stuff for manual piloting (again, like the recent movies or Discovery), but when there's just a TV screen it's pointless. You're essentially piloting a videogame ship.
If you start applying logic to Star Trek designs, soon you're asking why the Enterprise is the silly shape that it is and everything comes crumbling down...
In science fiction and fantasy we always work with "degrees of realism". Throwing it completely out or dismissing it as an argument only because the universe isn't 100% realistic is, imho, like throwing out the baby with the bath water.
