Government Shutdowns weren't historically a thing until recently.

There was no such thing as a government shutdown until Jimmy Carter's attorney general made the whole idea up in 1980. Creating a new law out of whole cloth by misinterpreting an old law from 1870.

No sensible country does things like this. In parliamentary systems, failure to pass a budget usually means an automatic vote of no confidence and new elections, while the government keeps ticking in the meantime. That is probably the best way of doing things — but the pre-1980 method of just leaving things going as they were if no budget is passed is still far superior than the current shutdown-prone mess.
