It would be a capital idea to capitalize on the common misuse of "capitol"

Events of this week have revealed a horrible patch of ignorance in the United States, one that is usually undone in grammar school. This classic homonymic error happens a dozen times before breakfast in your social media feed, and you don’t want to be the one with egg on their face. I speak of course of “capital" versus "capitol.” Capital means several things: it can refer to accumulated wealth (business equipment purchases require a capital investment), an uppercase letter (a capital “Q” delineates terminal gullibility), or a city that serves as the seat of a country’s or state’s government (the capital of Vermont is Montpelier). Capitol means only one thing: a building in which an entity’s legislature resides. Capitol is reserved only for the building, not the city where the building resides. The capitol is always located in the capital city. The capitalization of “capitol” is another matter! When you reference a capitol building specifically, like when you say, “I am going to storm the United States Capitol,” you do capitalize “capitol.” When you say, “My fellow whackadoodles are going to storm every capitol building in the country,” you do not capitalize “capitol,” as it doesn’t refer to a particular one.
