LOL, it's all good
I used to use copper paste a lot too and would continue to do so. Even usual grease where I knew the right screwing torque is not of high priority, I'm no one to throw a stone.
Served me well most of the time (not behind the brake pads though, the paste always "dried out" quickly).
It was just recently that a friend of mine recommended Chesterton 725 anti-seize compound
to me, and I liked the consistency of it. He's been through 750 grams of it by now, privately restoring motorcycles one after another (and being, iirc, chief mechanic at a WRC team) and I highly value his opinion.
He uses it on threads, exhaust gaskets, exhaust joints, brake pads and pretty much anything. It's hard to come by though...
It mimics the friction of steel on steel through a combination of nickel, aluminium and graphite, so torque to apply stays the same.
A different area: Grommets I sometimes furnish with silicone grease (used in coffee machines). Rubber gaskets of a flat-sealing type, I apply silicone oil, very thinly. A little goes a long way.
Not quite anti-seize, but somehow anti-sticky: What I don't use anymore is "Hylomar" or some such sealing paste, because it's a PITA to clean. Engine silicone FTW! That'd be "Loctite RTV Silicone" or, imho really good, "Würth Super RTV Silicone
And of course battery pole grease on anything electric.
But honestly, I'm no professional but a self-trained idiot and always open for suggestions.
