All these arguments would be soooooooooooooooooooo much more honest if the person just said "I don't like it and am just making stuff up to oppose it".
On the other hand, it would show soooooooooooooooooooo much more humility if you would just admit that either most people don't care, or use a system that works well enough for them.
The prices of many, if not most, things we purchase today are not particularly "sane". Diamonds for example are expensive because of good advertising and artificially limited supply. The prices of various stocks are frequently dependent more on wishful thinking, fanciful projections and following the herd than actual logic.
I base my prices (for the limiited items for sale) based on rarity. Is it a crap way of doing it? Of course. Just like every other method. I'm just pragmatic enough to admit it, along with being realistic in acknowledging that we'll probably never get a price list from WOTC or 5E's version of the Castle Builder's guidelines.
