Information is good, but it doesn't automatically imply that you have an actionable path in getting what's legally yours. Besides that, the Internet hasn't nearly eradicated the inherent information and attention asymmetry between consumers and companies employing people full time to make sure they end up on top for every interaction you have with them.

Consumer protection regulations, especially those regarded trading and credit, cast a very long shadow (ray of sunlight?) you're possibly unaware of, but still immensely benefit from.

Obviously there are diminishing returns and unintended/negative effects to consumers too sometimes, but throwing protections out completely in favor of a "pure free market" doesn't do these asymmetries justice.
