He has intentionally chosen to prioritize free time and freedom over cash-flow.

My read is completely opposite, he is sacrificing free time and freedom in order to obtain cash-flow. Specifically he is constraining himself to living within 10 miles of employement, and spend 2x as much time commuting to bicycle to work than take a car. He suggests spending time shopping, cooking, and cleaning to eating out (perhaps 2x the time of eating out, 10x time of fast food).

As with you I really can't argue that this is a wrong choice, but I will argue that this is not an honest argument. The cost of his frugality, in terms of time, is something never mentioned throughout the article.

I doubt he thinks of those things as "sacrificing free time".

I'd say those are more of a lifestyle choice than a sacrifice. He's prioritized free time and freedom to enable that lifestyle. It may look like a sacrifice to some but it's part of happiness for others.
