Removing the Star system, regardless of it's shortcomings and the trading unfairness, will still not lead to any less arguments. It's just a visual representation of an underlying problem, nothing more. The real cause for arguments and fights over trades lies in the number of goods offered/demanded and cross trading.
Changing the ratio's only changes the numbers people will argue over and there will still be hagglers trying to sneak in extremely unfair trades.
The best you can do is altering the production rates so that 1:1:1 becomes fair (in terms of space needed), and setting the trade system to have a much stricter limit on how much extra you can demand. The repercussions this will have on the Tech Tree etc I will gladly leave to the devs to consider.
Of course, this kills all flexibility in trading and likely even creativity in city design. Even then, arguments/fights will still occur.
