You are forgetting another important factor: not all laws are just or make sense in the current year. Less than a generation ago we had laws that oppressed black and gay people. I doubt you or anyone would defend these laws now just because they happened to have been ratified laws. Non government entities oppose or try to influence existing laws in many ways and for many reasons. Some examples are BLM, congressional lobbying, and what Uber has done. Uber's fight is, of course, strictly for their bottom line, but the general principle of non government entities making change through non legislative channels applies. Finally, you have to consider public opinion. Uber has had plenty of opposition, but I would say that, by and large, the public supports them because they provide a useful service. Your proposed "murder for hire platform" is both already illegal and would meet staunch public opposition. If SESTA passes we will not only potentially criminalize many software projects, but also make some markets impossible to enter without a sizable amount of cash (ex: web hosting).
