Perhaps, but I don't need to pay 10-20mil in accessories for Mastela Fruit to be useful, I could simply use a couple of Safety Rings (+6 def), or a Safety Ring and an Armor Charm (+8 def total) if I'm using Padded Armor(7 def), or 2 Eye of Dullahan (8% reduction against undead monsters). I'd rather have burst healing than have to spam the hotkey I have the healing item under to survive. They might cost more, but they'll last a loooot longer.
