Maybe people mean something else by counter-culture, but here are examples from my life:
- Freelancing/contracting, and actively living substantially below my means. This has given me free time in a way that really changed my view on the world and allowed me to be around other people who were not in the 9-5 working world.
- Sexuality & ENM, plus living in a large city. There is a huge non-obvious culture of LQBTQIA people in this culture which often have very different outlooks on life to the mainstream.
- Communal living. Living in a warehouse with people from very different walks of life. I was exposed to so many fascinating ideas and people this way. It was a truly magical time of my life in which I also played a part in supporting the queer/ENM sub-culture of my city.
- Buying land and living off grid. There is a whole sub-culture of people doing this, both online and (more importantly) physically around me.
So I think counter-culture is available but – having written the above – I'm not sure if I am agreeing and disagreeing with the OP. On one hand it exists, but on the other hand I'm saying that it is very hard to access without making material changes to one's life.
