There is a active push to limit the scope of socially acceptable venues to approach a woman

Whenever a woman says the acceptable way to approach and meet women is to join clubs or hobby groups I will remind them how that worked out for gym clubs. Gym clubs were once seen exactly like that, a social space for recreational (leisure) activities. On paper they seem a great way to meet women, right? A shared space where people with a affinity for physical fitness break sweat in their past time. But these days flirting or even approaching women in gyms has become openly discouraged, seen as inappropriate and even policed.

How wouldn't your advice to "join a hiking club" hit the same fate once enough women would get fed up with men trying to use it as a venue to approach them while they just wanted to learn rock climbing? Or a book club for that matter "these men are invading spaces to hit on women there"?
