(1) According to Art. 10 Para. 3 of the Swiss Federal Collective Investment Schemes Act (CISA), qualified investors are considered:

(3) A high net worth individual is someone who can confirm in writing that they directly or indirectly have net financial investments of at least 2 million Swiss francs.
Either way, you've again side-stepped every salient point. It's fine to have a philosophical disagreement but we should be able to discuss the facts at hand. Philosophically I don't think the government should be able to tell people what they can and can't dump into the rivers because it's in their interests only to drop safe stuff in there. Reality, however, indicates that in fact that's an awful idea and we shouldn't let them.
Sadly, facts get in the way of philosophy. That's why we have regulations.
Either way you fall prey to the classic libertarian fallacy, that an individual doesn't affect the society around them in any way. Yeah you go broke investing in the South Seas 2.0 company, or BTC at $19K. Cool. You own and sell property at a loss, now you affect your neighbors property values. Now you're on welfare, and on medicaid, and now all of society has to pay for your poor investing decisions. The law is how society mitigates this risk.
