Territory and Conquest

So I've asked this question awhile back but I've figured that since the beta has brought lots of new players, it would be a good idea to mention this again. I occasionally like to play this game called Elite Dangerous. Which is basically a space exploration game. And in this game, there are many different powers and factions that you can pledge to, or you can do your own unofficial faction. And with these factions, you can take over many different star systems and such. So the reason I brought this up is relatively self-explanatory. The world of sea of theives will be constantly expanding and getting more in depth correct? Well what if Rare decided to add factions to be in control of multiple different islands and outposts. Or even better, what if you yourself could claim unexplored islands or steal territories from other crews by planting your own custom flag on the island? I think depending on how the devs would do it, it could be either a really good feature, or a bad mistake. I'm curious as to what you land lubbers think it would be like. Is it a good idea? Say so. If it's a terrible idea, criticize me. I'd like to see other people's opinions on this.
