There is fraud prevention (yes, you being careful, and more importantly, only doing transactions with parties you trust to reverse in the event of a mistake), you've just been accustomed to outsourcing this to a third party for some expected added value.

Using that ridiculous definition, there is no conceivable method of transaction that DOESN'T have fraud protections in place, which makes it a meaningless distinction. When people say that a system has fraud prevention methods, they obviously mean something on top of some vague notion that people shouldn't send money to people they don't trust.
