I'm for social democracy, but it seems like you still don't understand the difference between private and personal here.Marxists always need a a crutch to work themselves out of their own logical inconsistency.
I officially proclaim all my private belongings to be personal. I've licked all of my doorknobs - by law of transitive property my house is now my toothbrush.
You aren't either making capital or producing products from licked things (how unsanitary), you would have turn everything you personally own into a toothbrush for no reason.
