That doesn't make lotto better than startups; the lotto is obviously objectively much worse. But the financial outcome of an unsophisticated investment in startups is likely to be worse than a lottery ticket; if you buy a bunch of lottery tickets, you'll get something back. If you don't know the industry, investing in startups is like throwing your money away.
I think something people don't consider in these discussions is that the current startup ecosystem --- the one in which the majority of companies return zero to their investors! --- is the product of relatively sophisticated investment. It's not impossible for a huckster to get funded, but it's troublesome enough that truly fraudulent companies are the exception.
All that changes once you set up a structure that allows people to "fund" companies "retail".
