Bandobras Took
Emperor
That's 2/5 of the things it does. The other 3/5 (culture boost, espionage boost, small economic boost) are also pointless compared to what you're giving up.
A Great Merchant?
There's no guarantee Free Market's going to do much if people are in Mercantilism; Castles give +1 Trade Routes anyway, so Corporation won't make much difference, and Assembly Line also requires Steam Power anyway.
So the only point of getting Economics early is to get a free Great Merchant.
If your game needs a free Great Merchant, you've probably got as many problems as somebody who needs a Castle's power graph boost.
