The reason why we have things like regulations and consumer protection laws is exactly to prevent people from, as you put it, becoming victims of themselves.
If everyone had this kind of attitude, we'd still be driving cars with no seatbelts.
Yeah, except that car manufacturers started to put seatbelts into cars before regulation. Similarly with all other protection systems. Regulation made it ubiquitous and that's great, but don't mislead like this.
It's very easy to become a "victim" of yourself even in a regulated world and I assure you the number of people who do will not go down, only the means of doing so will change. Perhaps we should focus on education instead of regulation.
There's a reason that we term things like power and water "public" utilities, and that decent, well run governments regulate them. One, it's to ensure safe, reliable supplies. And two, to make sure that they're fairly priced. What happened in Texas shows the complete and utter failure in this regard. Sure the citizens of Texas voted for this complete clusterfsck, but not everyone, and those who end up with the short end of the stick shouldn't be blamed because the majority were a bunch of idiots fed lies for decades.
