But was held back by:
1. A relatively weak fruit.
2. Stupidity
Think about it. Kaido even as a teen only had a 70 million berry bounty. Luffy didn't become powerful until 19. Shanks? Was an apprentice alongside Buggy in his teens. Oden? Strong, but still not on BMs level.
BM had a bounty of 500m even as a little girl lol.
None of the top tiers we have seen were anywhere near as dangerous at a young age
