Proportional representation is never harmful

When we think about which voting system is the best we can assume that the electorate are not communists and do not want a (big) state. If they want a big state no voting system will be able to prevent it. So we might as well assume people want a small state... in which case pr is preferable and fptp prevents the people from reducing the size of the state. If fptp doesn't prevent the people from reducing the size of the state then the people are communists and it is hard to see how at least one of the parties wouldn't pander to that. Clearly the people are not communists... (they would be able to get communism under any democratic system... and they have not chosen to do so) and so then pr is preferable. Only if the people are communists would fptp be preferable but even then it would be able to offer very little protection. It would only be good if the people are stupid and vote for one of the parties out of loyalty. There is no reason to have fptp and even if the people are communists (which they are not) it would be able to offer no protection. And since they are not then pr is better and fptp can only be bad. Under no circumstances is fptp better and (since people do not vote out of loyalty) it can only produce more government than pr. There are no circumstances under which fptp produces a smaller state than pr would with the same electorate. Fptp produces a government of either the same size as that which would be produced under pr or larger. Pr governments are never larger than those produced under fptp.
