Exactly. I was thinking about that person's opinion about the Camino when I read that thread of yours.
Asphalt, villages and cities, infrastructure, civilisation and people is usually not exactly what wilderness hikers are looking for in their walks. Some of us enjoy both Caminos as well as wilderness hikes for what they are, but when you can't get away from your expectations, the classic Caminos must be disappointing to those who prefer "classic" hikes (and probably vice versa).
Funny thing is that I'm the fool between both parties, as I do camp on my Caminos.
The pilgrims will say to me "Are you mad to carry all that extra gear when you could stay in a comfortable bed in albergues or hotels!?", and the hikers will say "Are you mad to walk those ugly crowded paths and to stay in campsites when you could also walk through nature and wild camp for free and away from people and noise!?"
But I think some people, like me, do enjoy the mix of both.
Some enjoy the more remote "wilder" Caminos, but still prefer to sleep in a bed each night. That's quite common I think.
Some want to walk the busier routes like the Francés with its social component and good infrastructure, and still enjoy sleeping in their tent. That's more rare.
But I think as long as camping is done legally (or in case of emergency bivouac, respectfully without damage to nature, animals and locals) it's all fine.
