Yeah, everyone wants made drinks, not to make drinks. Some people just want those drinks enough they are willing to do the making themselves. A very small (proportionally) subset of those people discover they really enjoy making drinks, and get into bartending/mixology. I love a number of cocktails but can't be assed to have all the ingredients handy and actually make any of them.

If I'm mixing a drink at home more complicated than putting something carbonated into something with an alcohol content it's like a bit of like juice or a fruit garnish as a third ingredient. Maybe over ice. Because much as I'd love a martini or old fashioned I'm not stocking bitters or vermouth or whatever on the regular, and those are even pretty easy drinks to make.
