In my opinion, the removal of the market should be a galaxy option mainly surronding the notion of a SS galaxy.
Currently we have 2 SS galaxies that have been played recently in SN and Infinitium.
SN is a hardcore galaxy with UA/IA and the market should be a part of this.
However (in my opinion), Infinitium is a normal galaxy which has replaced mathano (as in it is not available anymore). In a normal SS galaxy, I believe the market should have been removed prior to the start of the round so it could be treated as a pure SS galaxy where old and new players could play around with the game on a relatively even playing ground. Saying this you can’t simply remove the market form Infinitium due to the fact people have built strategies around it as Lurker states above.
In my humble opinion, a hardcore SS galaxy (single player fams) should have the market and people can do what ever they want in relation to market aiding. However, in a non-hardocre (normal) galaxy they should be the option to remove the market to purely make the galaxy SS as in self sufficient and maybe could be looked at when starting (or re-starting ) a SS galaxy
Just my 2 cents
