Ok. Then my parliament should allow 1/68-millionth of vote to every French people. Usually the counter-argument is “But people will vote for themselves! They will vote stupid laws without informing themselves!”

So no, democracy isn’t the ability to govern. It’s the ability to change those who govern, once every 5 years, i.e once every 4600 laws.
