'Hard use' knives have a different spine thickness, primary grind, blade shape, tip strength, etc. They cut differently from light users. Expensive knives have no such distinction. They are either expensive hard users, or they are expensive light users. But, they are still expensive. People spend whatever they want without necessarily changing how much force is required to cut & slice. One is an issue of what we want our knives to do, the other is an issue of what we want our knives to represent. Tangible vs intangible. The line blurs in high-end production or custom, but it's there.
Someone could buy a CS Lawman, or they could get the custom version from Andrew Demko. Someone else could buy a Case swayback Jack, or they could buy one made by Tony Bose. One guy wants a hard use knife, one guy doesn't. These guys either spend a lot, or they spend relatively little. It's doubtful either one would be happy with the other guy's choice for whatever the job at hand is, regardless of cost. Choosing a 'sharpened prybar' or the new derogatory term 'cheese cutter' is a matter of what you want the knife to do, not what you think about the expense. Both kinds of knives are represented at all price levels.
Hard use has nothing to do with mere excess. It is about tradeoffs in actual cutting, prying, or other. Relative to the 'typical' knife, excessive ability to be pried with means relative loss in ease of cutting. Excessive thinning of the stock or grind angles for ease of slicing means a loss in ability to take lateral force. Excessive spending on a knife doesn't do anything of the sort.
"Hey, don't criticize my wanting hard use, you spend a lot of money on knives." I don't even know how a guy who pays Strider, Carrillo, or Hinderer prices could say this. Those are both hard use and expensive. If the premise of this thread is asking people to look into the deep down question of 'Where do you get off saying X when you do Y.', then what do we say about the guys representing both?
