You want to make market-making unprofitable and to turn the stock market into your town's real estate market. How easy is it to sell a house? What is an accurate price for your house? At this moment? To the dollar?

Real Estate isnt comparable. There are no market makers in real estate because the product isnt standardized and you can't make an equivalence market in one-off products... Houses aren't securities and the illusions propagated by securitizing the loans around them clearly has wild historical market risk attached.
"it is a sophomoric attempt at solving a human problem that simultaneously guts the actual mechanics of exchanges."
Markets are human constructs...the pure mechanics of exhanges aren't more important than the humans they serve. Fixing the human problems should be the priority, right?
There are lots of legitimate reasons for behavior that looks just like this. The problem is not one of technology, it is purely the intention that causes the problem.
Those canceled orders had to be listed, the bid-ask system had to transmit them, matching engines had to consider them, cancel machinery had to back them out, and price discovery is affected. Why shouldn't one pay for the costs incurred?
Finally, none of this has anything to do with spoofing, because spoofing doesn't need high cancel rates. If anything, making cancels more expensive will encourage the behavior, because it will make traditional market making more expensive (either explicitly or implicitly by requiring membership in a cartel to be a market maker). Meanwhile, the spoofers trade is much higher margin and can absorb the new extra cost more readily.
