Like, every golf course here in Shenzhen, which the lowest cost deal for a membership is over $100,000 USD for the entry-level membership, and if you want access to the elite courses, you're going to pay more than $350,000 initial fee to join. After meeting this initial fee hurdle, then you get to pay the monthly maintenance fees ~$1000 USD and also additional green fees on the weekends, if you didn't buy in at the highest level. There is definitely a market for real life premium social clubs but I'll be suprised if it translates to an app.
