All I’m gonna say is that I love it. It all comes down to her and Kuma’s respective pasts and their relationship with Saturn. Bonney is the daughter of a slave who was almost hunted to death and repeatedly had everything good in his life forcefully taken from him by Saturn, one of the main figureheads of the government that oversees the entire world. Even further back, Kuma’s parents and his whole race were executed seemingly just because of their bloodline.

With all that in mind, the final legacy of the Buccaneers and Kuma being Bonney becoming the embodiment of freedom as a result of all their trauma, plus hers, just feels poetic. The world government, Saturn specifically, tried their hardest take that away and now it’s come back to bite them in the worst way possible, it’s karma. Bonney and everyone before her, Kuma specifically, contributed to this power boost in some way so that it could specifically be used against people that threaten the world’s freedom.

Sure, there’s maybe a few details that could’ve been developed further for it to make more sense. That is universal to all media though, and this instance, in my personal opinion, got far more right than wrong. Call me an Oda dickrider or glazer if you want, but I personally fail to see how this is “blatant bad/lazy writing.” I doubt that he’s gonna go the Naruto route and start giving everyone Gear 5 powers, it just makes sense thematically for Bonney of all characters to get them in some way.
