But Trads perform a useful function of reminding us of possibilities that repel our modern minds otherwise
We shouldn't let modernity constrain our imagination
E.g. The best form of govt is where each man has one vote

In early 20th cen Britain this was indeed the case!
Alternative notions of morality contrary to the "live and let live" modern ethos
In their absence, you just end up talking to fellow progressives and constrain your field - totally precluding any reversion to a historical state
