There are many layers and interpretations of confidence there that you mix up. I’m assuming this works somewhat like where I live. Its the confidence that the government is in a functional state/working somewhat efficient vs the confidence of fair elections. There are mamy ways where parties can essentially block progress or the government in general. That’s somewhat fine and can be an important instrument to use (especially when in the opposition). But that doesn’t necessarily mean that the people causing it want to get rid of fair and free elections. Some kind of “shutdowns” and other grind locks can be very detrimental to a government and there need to be a mechanic to be able to solve them. In this case: We have no confidence the current parliament with the current distribution of seats is working as it should be. We tried everything, we need to restart.
Since it’s a quite drastic process, it’s not something invoked lightly.
That still only counts as one!
