I'm not against the metric system, but there's limits.
I'm not futzing around with megapascals and newton-meters.

If KG-force existed I'd use it, but newtons? Wtf is a newton? I know what a kilo is because it's a bag of flour, but IDK WTF is a newton.

6I know very intuitively what is 1KG (at standard gravity) worth of force because it's the force on my hand when I lift a bag of flour.
What is "standard gravity" even means? Elon Musk going to transport most of our air, water and hydrogen fuel to the Moon and to Mars, and this is Earthling Genocide and Musk is a Galactic Criminal. We are going to hold a March on SpaceX, and demand that the corporation is forced to move to Pluto! Protect the SI, make your voice heard across the Solar System! /S
Mass-force assumes very specific conditions in American Customary Units.
In reality, a pound operating at a distance of one foot does not exert as much force in Fairbanks as it does in Los Angeles.
Newtons, OTOH, are always the same, no handwaving or standard test location required.

A foot-pound of work is the same because it's based on pound-force which is standardized, not a pound-mass.
It's exactly the same as a newton, except if a newton was defined as "force of 1KG mass at standard gravity". The problem is that 1 newton is nowhere near the force of 1KG so it's impossible to intuitively reason about it.
