Hello,
in my opinion the license-based reputation changes can have a negative impact on gameplay, namely in
1) trading: it would be impossible to trade in areas patrolled by hostile factions, and more difficult to choose the way for long multi-system runs;
2) upgrading: it would be impossible to buy a specific ship or piece of equipment sold in only one place if the base owner says "you must be on friendlier terms" (this also applies to containers for trains);
3) exploration: it would be harder to map all systems in Sirius when some factions are hostile because of your license.
Together this can result in considerable inequality between different RP sides by introducing limits or inconveniences in non-RP (!) aspects of the game. And since clan members would be doomed to live with certain limits, this might even discourage new players from joining clans.
QuoteOne one side its more realistic and for sure more interesting ... on the other side it limits the players and the regions where they can go to.
Guess I just described the second part of this sentence in more detail 
Anyway, the idea is that while realism is a purely conceptual improvement, it can cause a number of very non-conceptual in-game problems like mentioned above - and feeling more realistic is not an adequate compensation for them.
Besides, outside RP situations all players must have equal rights and freedoms - that's how it should be on an "Open RP" server... I think.

sorry if I repeat what someone already said. 
Have a good day!
