and no, this is a convo about a faulty analogy: a universally objective, tangible entity (kilogram, speed, feet), and the services that money renders.

I really hate this as advice in general. I'm under no obligation or need to coddle people in their understanding. If you don't understand it, I don't have time (or effort, jeez) to explain it to you

Money Isn't a Measuring Stick, Idiots (TDE, Pete Earle)

I believe you misinterpret what is meant by a fixed measuring stick.
That never implied products and services are going to have a fixed cost in perpetuity.
At best this is a discussion about semantics. 

"Tl;dr: Y'alls suck at thinking about money, even though that's what you do all day long! Please be better."

And this is not friendly remark and certainly not a good strategy if you are trying to convince people. At best it's good advice to yourself. 

Be better.
