Logical fallacy. Devil fruit works in a similar way. Didn't Blackbeard casually use gura gura no mi, and Sabo with mera mera no mi?
Can't you identify the differences among Blackbeard, sabo and MOMO. Anyway lemme break it down for you.
BB and Sabo:
-They were full grown men.
-They never cried like a baby.
-They were physically powerful.
-They have enormous courage, Blackbeard invaded impel down and marineford without gura gura fruit. And sabo neg diff burgess and wreaked havoc around just before eating mera mera fruit.
-Dispite these feats, sabo himself mentioned that he would need to master mera mera no mi.
- They have fought battles with powerful opponent and have a lot of experience.
- They use haki .
- They can use weapons.
And if you still think that momo's case is similar to BB and Sabo then I couldn't help you more.
