We absolutely should sunset those laws.

If they are needed they can be voted upon again by parliament, and will no doubt pass.

In fact I would say not only should all laws have built in expiration dates, such expiration dates should be shorter the lower the percentage of votes in parliament it too to pass them!

If you can only get a 51% majority in parliament to pass a law, that law should not exist beyond that election.

I see you've never played Nomic. Laws that automatically self-destruct are a very clever way to create the conditions needed to win the game. You should try it some time.

Sounds like a huge waste of time to me.
