Because the system you're passionately defending via the "personal responsibility" angle has so far demonstrably shown itself to be susceptible to the same externalizes of greed, avarice and "fuck you I got mine" misbehavior as the current system and people are lining up in droves to have their chance turning the grinder as long as it means they get a ticket to the sweepstakes.

And the responses you're giving of "just be risk aware/just read the source code/just know what you're getting into" doesn't change that, doesn't educate the people who probably and realistically could benefit, and it doesn't change the fact that there is a LOT of obfuscation, misinformation and mishandling of trust going on in order to separate people from their actual fungible money.
