He didn't. Posting about why Luffy wasn't able to and equating it to Momo at the moment is fine, but I specifically said that I think Momo will be at a greater state of preparation in the future and I've also brought up Shanks and Buggy as examples of young pirates on high level crews. Thus, the thesis of my response was that I think Momo will be a character capable of doing so after Wano. You responded to that (even if I disagree), SeaOfHope did not, so he didn't really respond at all.
Oda has been preparing Momo for his big moment for a long time now. He's definitely going to wield his father's sword and he's a dragon for some reason. We've seen him studying the sword, we know he's been influenced by three of the greatest pirate crews ever, and he's being prepared not just to man up, but to fight for his dream. I'm only 50/50 on Momo joining the crew, but I think that 100 percent he's going to have some impressive combat feats by the end of Wano, whether it's through some time hijenks or just because of all the small ways Oda has planned it out.Being aware of danger doesn't equal being adequately able to overcome it.
It took Luffy ten years of training to be ready for adventure on his own. Momo has weeks, at best.
Sanji already validated Momo's bravery. But Momo still has to be protected by Shinobu, Kin and the others: his safety is of utmost importance, and he's physically unable to go up against Kaido without putting himself and Wano's future in major peril. Momo, Tama, all these kids, they aren't ready, their moment hasn't come yet.
Carrot is realistically just a few years older than them, but she has proven that she can protect herself and others. Yamato has that capability, as well. That's one of the things I personally look for when thinking who could work and who couldn't.
