The quote literally says "and I'm happy to talk to them."

This is about flexibility and a change from strict 9 to 5 office hours. You can't have your cake and eat it, too. If you're not available from 11AM to 2PM, you still have to complete your work - maybe you don't need a full 8 hours to do it, but it needs done.

Naturally if client calls aren't your thing, steer away from that kind of work. Maybe instead you don't mind writing code at 8PM or doing research at 8PM.

When you're young and lonely and clueless many unhealthy/unsustainable things can make you happy. Happy isn't the be-all, end-all of how work should be structured. Many people regret making tradeoffs they were once quite happy to be making.
