Why Western allied nations in particular? I'm also not sure that list is as universal as you think. For instance, the no drugs thing would likely not apply to the Netherlands.
Simple: Western nations are a somewhat coherent cultural sphere.
Adding in India (with its current war against Twitter and anything that dares criticize Modi), the Arabian and other dominant-Muslim countries (women's rights, LGBT, democracy) or Russia/China (which are essentially dictatorships) into consideration would add way too much illiberality to be acceptable.
