Take a look at the USA where mandatory minimum sentencing [1] is in effect for drug offenses - once a ludicrous maximum is set, all it takes is another measure to put a more "reasonable" minimum and make it mandatory... the Overton window [2] principle applies very well here.

Economic theory as applied to criminal suggests that sentences must be harsh in inverse proportion to the probability of catching a given criminal, in order to eliminate the 'producer surplus' of crime (potential gain/ (potential risk of capture * loss of sentence)). Of course, the weak point of this theory is that law enforcement has a strong economic incentive to prosecute easy-to-prove crimes like drug possession; another issue with it is that the public perception of crime risk and severity isn't very well correlated with the actual risk, and historically people are not very interested in what happens to criminals after conviction.
Since the costs of a trial are so high, most investigations result in a guilty plea in exchange for a reduced sentence and the public cares even less about people who say they are guilty. The public is somewhat interested in the claims of the innocent, but then again many assume that there's no smoke without fire and resent defendants' use of taxpayer-funded resources to conduct long trials and lines of appeal. American law is so procedural that trials are very very slow compared to most other countries, and so expensive and challenging for both prosecutors and defense lawyers that only fewer than 5% of charges go to a jury trial; the rest are settled with plea bargains, bench trials and so forth.

Clearly the current system is not working well at all and is creating a great many injustices of its own, but there's very little legislative mileage in saying that. I was quite surprised that Congress passed the legislation eliminating the disparity in crack/cocaine sentencing in 2010, given that crack dealers have been the criminal bogeymen of choice for so long.
If there's enough mass of people realising that the government and copyright cartels are bullshitting and using pirates as a bogeyman for economic problems, then the people will vote them out.

So the winner take all would remain for a while.
But besides direct democracy (which has many forms), there are forms of representative democracy far more democratic. Like every percentage matters, so if a party gets 3% nationwide he gets 3% of the seats, instead of losing it to a "winner takes all" scheme.
