I did not used to think this. In 2007 British Columbia had a referendum on switching to proportional representation from FPTP. The result was like 52% in favour, but the government had set a minimum of 55%,so it did not pass. I thought it was a a terrible idea at the time (the people had spoken! Democracy!), but I don't think so anymore. Another example is the 1995 Quebec independence referendum, which "stay" narrowly won, but afterwards the federal government passed an act making it much harder to pass a referendum.
Basically, the bigger the question, the longer and larger implications it has, the more it has to be thought through, the more consensus there should be. The US constitution has features like this when it requires large majorities to pass amendments etc.
As an engineering metaphor, having a fast-response system without any dampening can lead to out of control oscillations, which ultimately destroy your system.
