It's less rule by consent and more rule by mob. Just because 50.5% of people vote for something I disagree with, doesn't mean I suddenly consent to it being law. I still don't have a choice and must unconsentually comply, otherwise "men with monopoly on legal violence" come and kill me or take me to prison. The only other choices are 1. convince the 1% (literally millions) of people to change their mind and get that vote to 49.5%, or 2. find a different place to live.
