If said fence was across a road that a school bus was hurtling towards at 60 mph… you’d stop asking these questions and remove it (and maybe put it back after you’ve solved the other emergency).
Several (of the new government) have expressed belief that the government is headed towards a catastrophic debt overload. In their view, emergency relief is necessary.
Not arguing for or against this view, but that seems to be what people voted for.
I am a big fan of Chestertons fence but it doesn’t always apply.
