No you can't say "the exact same thing" because a Wizard can actually get plate through another class or a race and a feat or multiple feats. RAW a Druid can't at all.
A Shield Dwarf Wizard can wear half-plate on day 1. A shield Dwarf Druid never can wear half plate even though he has proficiency from both his race and his class.
Class __ should get __ buff because it would be stronger and the player wants it.
The point is that it is just not a statement that can be discussed. People wanting the Druid to wear metal armour because it is stronger is a non-starter.
Players can want all sorts of things, it doesn't mean they should happen.
We just started a new game and the Moon Druid player talked to me about how they felt they were too constrained on their prepared spells per day and wanted a way to change them up more often. I said if that is a concern play a Land Druid. It's not good for the game to just have all the things.
