Daima is the perfect explanation for why Bulma makes frivolous wishes in Super.
Oh Bulma should just save them in case of an emergency. Nope Neva summoned them from all over the planet also everyone knows where she lives.
Why not just use one wish to put them on cooldown at least. Shenron grants multiples to repeat users and multiple villains have used the Dragon Balls.
Why does Bulma just preserve her youth instead of wishing for more practical things? Because she enjoyed becoming young again in Daima but she canโt be a child while being married to Vegeta.
Maybe in the future when they both reach the age of 80 and Vegeta starts to age theyโll agree to become kids again and live as pseudo-immortals.
Not to mention, after what happened with Frieza in DBS.
She probably thought it was a good excuse to make such wishes.
She doesnt really need it. She is the richest and smartest woman on the planet.
So I think she is just doing it for fun.
