Lava waders aren't especially good if you use beenades, because beenades don't release bees if they explode in lava.Or Just Use Lava Waders If You Can Find Them. Or Just Get Every Sliver Of Iron You Can Find And Make A Gigantic Minecart Track Spanning The Whole Underworld. Overkill? Yes. Time-Consuming? Yes. Satisfying? Y E S.
Also he probably doesn't want to spend 1 and a half hours hunting for a lava charm and then another 1 and a half hours AT LEAST hunting for water walking boots.
Tbh if you reach the end of your bridge again just use a water walking potion, much less time consuming then spending so much time on a stupidly rare item you'll only use once.
