I kind of assumed that his comment was independent of the meme he posted and served more to underline a perceived power that vim has over other editors. In this case a power OP doesn't even understand/use himself.
On the other hand, there are places, where it's so easy to get weed and other drugs even today and delivered directly to your doorstep. In those places it may be easier to stick with your dealer for procurement and enjoy the benefit of decriminalization of possession and consumption than going through the hassle of joining a cannabis club. This in turn would negate some.of the discussed benefits of legalization.
It's not really clear, who of the two the text refers to.
