Rules and regulations won't stop all accidents because in the end there has to be a basic assumption that you come to the party with a basic level of skills and a mindset that has some level of self preservation.
From old blokes willing to bullsh1t an air race entry form in a cut up P-51 Mustang to two commercial pilots willing to lift and immediately destroy an AW139 in poor viz. At some point the line is drawn somewhere and if there was commercial pressure then making more piloting rules and regs isn't going to help.
