This week's hypothetical scenario:

[Knjaz]

So, what would happen if, for example, a new player would need to have a X amount of time online on that character's IP in order to be able to buy a Pirate ID (Covers the Generic Pirate ID, Outcast, Corsair ect) to allow the player to familiarize himself with the RP of the lawful side and encounter pirates on the receiving end.

How are you going to implement it technically, so "old and experienced" players would be still able to create new pirate char when they need one?
Different solution would be to significantly increase the price of unlawfull IDs, so every new player would be forced to "RP" a trader/miner, and know how does it looks from the other side. But then again, it will impose additional restrictions on old players.
