I dunno... since cantrips are the result of particular life choices and a dedication to those choices, not just something every fisherman, camper, hunter, actor, being lacking good night vision, or what have you can just "pick up", is there actually any harm?Need to go fishing? Just head to the local fishing hole and shocking grasp.
Why use flint and steel, or matches, or firestarter? You have a Fire Bolt. Do that.
Hunt with Eldritch Blast.
Why bargain for goods with that merchant? Just cast Friends.
You're an actor who no longer uses makeup. Just Disguise Self.
Lanterns are useless. Cast Light.
The list goes on and on.
It's not typical for a wizard to need to go fishing, and if he does and decides to get in the water and grab the fish with his electric hand instead of using a pole... so? Doesn't sound any different than getting in the river and grabbing a fish by hand in real life; there are people that do it, but not everyone does.
And if you are a wizard and you can't even start a fire with a snap of your fingers, you are failing to live up to the expectations generated by most sources of fiction regarding wizards.
I won't harp on the rest except by saying this: You are effectively saying that you expect a significant presence of what is the equivalent of doctoral graduates choosing to work in food service, but being pretty good at it, and that you find that expectation unpleasant.
Just like doctors are heading up and down city streets making sure everyone they see is healthy, D&D spellcasters are providing the world free benefit of their magical abilities. Maybe they too have insurmountable student loans to pay off?
