Bohm that is exactly what the commission does, it creates binding regulations and it determines all legislative proposals. But you are wrong it is not 'democratically' elected by the 'people'. Effectively the people's elected representatives do not get any determination on policy.
The commission is not elected democratically, true, but it is appointed every 4 years by democratically elected heads of state and confirmed by the EP. You have to compare this state of affairs to other non-elected (but appointed) positions in every single western democracy.
That "peoples elected representatives do not get any determination on policy" is FUD. The commission cannot make final decisions on EU law or policy. I would strongly advice you not to rely on the leave-campaigns talking points.
