I prefer Currency as the first solution to my economic woes, because it enables me to optimise for the long term (production first while important infrastructure is still to be built, economy later). If we assume that forges and courthouses and forges are the highest priority, forge first is faster to get us to both. If economic infrastructure follows (libraries, markets?), we'll get each of them earlier, meaning we catch up a little on the additional maintenance we paid.
Pretty much the only cases in which I make courthouses a high priority:
- exploiting a temporary military advantage, leaving me with more cities than is efficient (but I don't want to delay conquest because my edge will disappear). Whip courthouses to deal with the crippling maintenance, worry about everything else later. Something similar MIGHT happen if I power-rex because I fear being boxed in and there are no convenient choke points. Hasn't happened to me yet.
- I want to make espionage a cornerstone of my strategy
- I got CoL early for some strategic reason beyond general economy and my economy is strained enough that I can't get to Currency in a reasonable time without them (something-for-nothing tech, meaning snowball effects possibly even nicer than an early production boost)

@ Crusher1: Imo, there are few problems that can't be solved with more hammers. Researching the entire religious line and building the Oracle for Metal Casting usually doesn't take more citizenturns than researching it by hand. Quite possible for non-Industrious leaders although simply viable instead of a huge advantage. The only question is: Do I have something more pressing to do (secure the Great Lighthouse, block off several AIs, kill someone, research many different resource techs beause I got a very mixed bag).
As I have said, I tend to view Currency as the primary recovery tech rather than Code of Laws which allows me to build wealth meaning forges help there as well, in case my economy is truly strained and selling stuff isn't enough.
