No one is debating the idea of a standing military today, but we should be now and they did back then. The same goes for a central bank, Hamilton and Jefferson debated this heavily and today we have something very much like what Hamilton wanted. We aren't debating banking but it's hugely important and flies under almost everyone's radar.

There's also the (maybe) obvious recent topic of liquor. A recent court ruling overturned bans on home distillation and way back in the Washington presidency they had to send the military to squash a revolt driven by a liquor tax.
