If you say so. None of the examples you provided require 7+ years additional school/training, impose the opportunity costs of not only having to pay for an education (other than MBA/JD, which are both shorter than MD), but losing income during school/residency, and, quite frankly, have higher upsides. Maybe not as compared to the person who is going to go on to run a drug company or a hospital chain, but compared to many of us who are going to go into practice working for someone else, many in primary care, or into academics.
I'm not a huge JD fan, but finance, tech, consulting, etc. are all significantly easier and often more lucrative than MD. I'm not talking about the hours, which are pretty intense anywhere when good money is involved, but the training necessary to get to the point of making money. Computer folks right out of UG make significantly more than residents will after spending around $400K to pick up the required MD. That's way easier in my book. Same for Wall Street or consulting, with or without the MBA. If you don't agree, we'll just have to agree to disagree, but I'm pretty sure most people, both in and out of medicine, would agree with me.
Medicine is a calling that can be lucrative. For people who don't hear the calling, it's a grind that often leads to regret and burnout, especially since there are more lucrative fields with significantly lower bars to entry, particularly for people smart enough and driven enough to be accepted to med school.
