I got my way into Republic eventually, and eventually started building a wonder as well, of course.
I wanted the Sistine Chapel - that boost of happiness isn't available any other way, so it's valuable even to a non-culture OCC. Income is very strictly limited in this game, so even 3gpt of lux tax or lux imports from Sistine would prove helpful in the long run.
