No. No no no no. You are just going back to the original point. Which is-
Some people, back in the day, wanted fighter who could cast spells. Voila- ranger. There was no reason for the *archetype* that you are describing (wilderness dude) to have spells!
This is the same as saying, "D&D has magic. At some point, thieves will need magic. Therefore, the default rogue must have magic, because otherwise, it's silly."
Then again, I find it hard to argue with someone saying that wilderness dude class requires magic- not because magic is cool, or awesome, but because it's realistic. While ignoring the fact that almost all variant rangers proposed (including UA, recently) fix the Ranger by getting rid of the spellcasting.
There's no "right" answer here- but it shows how confused this class concept is. I have to admit to being a little surprised that someone is advancing the idea that spellcasting is core to wilderness, as opposed to just being core to the whole ranger as "fighter with spells."
