Let's flip the question around. why wouldn't a country want to issue their own currency? Using someone else's currency means that you are subject to their policy decisions whether you like them or not.

Why would a country not want to be in control of their own monetary policy?

Ya, I get that at a high level. The problem is that I'm a noob who doesn't understand the details of what "monetary policy" entails. Thus I ask. :)

Also, if having your own currency is such a "duh", why is the Euro a thing?

@Tirous The expectation on the Euro was that the reduction in costs and problems given by using one currency was more valuable than the loss of monetary policy flexibility. But as Greece and Spain have shown, the loss of monetary policy control is extremely painful. If Greece was still on the Drachma, they would devalue it to increase exports and decrease imports. But they can't do that, so they have to repay loans in Euros.
