As mostly said in the article, the first and biggest expense is taxes. However, taxes amount heavily depends on location you live and possible tax optimisations you can use in your position. For example it may vary in 10x+ times between entrepreneur/nomad in low tax jurisdiction and hired worker in high-tax jurisdiction. Maybe it's smarter to choose country (state in US case) with lowest taxes/highest return than suffering from 30%+ cut. I agree with the author about skills in general, but not every thing we do apart from the job bring us joy and satisfaction. Sometimes it's more convenient to just pay for the work.
