Yeah I made the same decision learning Chinese. It's just not worth the extra time and effort relative to the utility.
Occasionally I still have to sign my name, so I specifically picked a name that a) was written the same in both simplified and traditional and b) had a low number of strokes. Like you, the only time this has bitten me is in hospitals and banks where occasionally they ask you to do stuff like write out your address. I sometimes exercise my dumb foreigner privilege and ask the clerk to help, but since addresses have a formal romanization method it's often fine to write that, and I've seen enough locals struggle I don't feel too bad about it.
