It's become quite acceptable (and even *strongly suggested*) that
keys are taken away from someone who's impaired by alcohol


Taken by whom? This is a slippery slope, especially in aviation. Letting
others stop you because they think you're inadequate to the task (whether by
virtue of being drunk, stupid, inexperienced for the conditions, whatever)
erodes the basic tenets of self-responsibility, which is one of the big
differences between aviation and driving. I wouldn't want that to happen.
