This exists, it's called small claims court.
A organisation can not buy millions of claims from consumers and the fight a full class action lawsuit without any of these people being involve.
If you want to sue CVS for selling you fake aloe go ahead, it costs less than $100 to file a small claims case in my state and CVS will very likely settle with you outside of court because it's cheaper than sending someone to court to defend the company.
There are many other problems with the courts that make the system I proposed currently impossible.
