Human cells do not even have cell walls, unlike bacteria.

If you're thinking of the cell membrane, then I wouldn't say the bacterial membrane is any simpler. The lipids used are slightly different, but that's not a question of simplicity or complexity. And for example Gram negative bacteria would have two membranes, which is more complex than the single membrane of human cells (though we have additional membranes around some organelles).

In any case, alcohol would damage our cells just as easily as bacterial cells. If they were exposed to the same concentration.
