It's not about removal of FR5. It's about making FR5 unusable in case of smugglers.
The shadow of FR5 is something that makes players very unlikely to play smugglers nowadays. FR5 should not be used to prevent smugglers from their roleplay, as it brings activity for both smugglers and lawfuls. It's killing their RP - that's the biggest problem of mine with that.
Hiding behind "but it will lead to the powertrading" argument is null here. If player wants to powertrade, he will find the other commodity, other route and other time to do that and it cannot be helped. Punishing players, willing to RP, for things other players do is throwing the baby out with the bathwater.
Look at FL-ER for example. It's no secret they moved away from Rheinland, as they were indirectly threatened with FR5.
