Inherent trader problem (trade good values)

[GooglyBoogly]

I think it is a bad idea. It would make it even harder to balance out the trade item recipies, and would encourage extra players to switch into trader late -game - making games take even longer.

You would have to be playing for over a rather long time (~90mins) before a normal tank could earn 'more' than an unhindered maxed out trader. And even then, like Gammagulp said:

Also the trader generate money from "nothing" while the gold amount of creeps, towers and factories is limited every 5 minutes.

this is very important.
