Explanation:
Without the separation of powers, maybe you could survive, but that's all you could do. You would PROBABLY be ruled by a king (not the Queen Elizabeth that shows up to all royal weddings type) with absolute power. Without an executive branch, there would be no one to actually enforce the laws, so because of simple mistakes or for just being a bad citien and breaking the rules, you will probably get killed, because jails will probably be destroyed.
I personally don't know how it feels like to live in a country without separation of powers, this is just my theory.
