I think this is good advice up to a point. Bitcoin is the best play for maximum optionality for your wealth, but it has little intrensic value. You can't live on it, garden with it, rear children on it, etc, so eventually leveraging your Bitcoin to get land is necessary, ideally without losing it all in the process.
The system is designed to make it difficult to have stable family life. We make it hard for men to earn enough to support their families and we give out rewards to women who leave their husbands.
We punish responsible individuals who can't quite make ends meet and give government benefits to those who don't even try, or aren't even citizens, from the taxes of the responsible ones.
I think people realize, even if only subconsciously, that protesting taxes brings the idea that taxes aren't a universal unquestionable constant into the zeitgeist.
We all can intuit that the state will prioritize making an example of anyone who threatens to shine a light on this fact.
