He is a pirate so thematically it makes sense but from a gameplay perspective its pretty overpowered unless there is reason to explain for his need for free gold. Twisted Fate gains free gold from his passive because his ultimate requires him to leave lane a lot. The free gold is a means to keep up with his laner. So whats Gangplank's reason or is just because he is a pirate so fuck it lets give him free gold?

Not really.
There are champions with good scaling and bad scaling and everything in between, and kit-power can be converted to a gold value. Basically: Riot can tax Gangplank's kit a similar level of power he'd gain from gold.
Riot taxed Gangplank's kit for his gold passive. Looking at Sion's HP, Lissandra's MP/5, and Jinx's AS it's pretty clear Riot doesn't have an issue with doing this.
All capacities of a champion's kit offer some level of power and should eat up some amount of their power budget as well, which is common-sense with design. What makes a champion overpowered isn't that they can do X, it's that they have more power than their power budget should allow.
Oakleaf Ranger1 votesHey who said you were allowed to use logic here. JK i think a good way to play around that thinking is to increase a champions weaknesses with their power budget. Possiblly making champions strengths more niche instead of being just an overall strong pick into any comp like i personally think gangplank currently is.
oSEXYPLATYPUSo1 votesyea its kinda weird considering tf passive use to give the team bonus gold. not just him. and ashe use to have a passive on her hawk shot that gave her gold income for killing a unit but theychange that but leave gp's intact , its just he can get extra gold from farming but he can do it aoe with barrels which really adds up and im really surprised i dont see him with a 
to stack it even more.
Hmm the reason why him and a lot champions don't go cull is because your laning becomes weaker because of it.
