Sure I would buy them.
The other issue I see with the "hunting pirates" part of this is what Pinko touched on. You go hunt pirates capture one, bring him back to the doc for reward and you get 1k. The cost of firing one heavy shot for me with 100 or more in all skill required and a 23% Alc bonus tali is about 10k per shot and you use at least 10 per pirate ship, at least, and that's if you don't use grape shot, only cannon balls to disable the ship. So you have just spent at least 100k and an hour or two to get 1k. After the novelty has worn off of killing pirates just for the sake of killing pirates cause there is really no reward, this part of the game will die out quickly.
