Exactly, politicians are payed to make decisions. I don't want to say there is no chance for corruption and / or other crimes, but to start a referendum for all and everything makes the system much more sluggish or even stops processes at all. There are good reasons to do referendums in special cases, but I still think it should not be the standard for many small decisions. I also claim that often after some time 50% of the voters are not happy with the decision, but complain about bad or incomplete upfront information or they were just not able to see mid and long term effects. So the bad guys are no longer the decision maker, which is wonderful for politicians, but other institution like press, populists etc. or just your neighbor.
