Awesome, so you advocate making it a pain for consumers to know what they pay for something because math is easy and you don't have to buy anything if you don't want to... makes sense
/s.
Unfortunately the world isn't made up of people with your vast intellect to do math and stop buying things. It is full of people who are duped, taken advantage of, and walked all over. This is why we have consumer protection laws (
https://en.wikipedia.org/wiki/Consumer_protection) in most of the civilized world. When companies are allowed to lie, cheat, and trick consumers, things like the US banking crisis happen. I guess that wouldn't have happened if everyone knew how to do math or just didn't buy a house.
It doesn't matter how easy the math may or may not be. The point is it obfuscates purchase prices to a meaningless point system. These virtual currencies were created by the gaming industry to facilitate exactly what I'm proclaiming... it changes real money into something that is meaningless to the purchaser and therefore psychologically disconnects them from the exchange of money for a product or service.
No one but Frontier confirm or deny whether or not they are attempting to bamboozle their customers and perhaps this is all a product of them getting in bed with consoles. We don't know if in-game currency is being forced upon them by consoles or if they are doing it because they know it will increase revenue in a quasi-shady way. I suspect the consoles force in-game currencies for store purchases in game because they likely get a cut of the sale and they know the psychology behind in-game currency. If that is the case, then it is in the console company's interest to force an in-game currency requirement on game manufacturers to... one again... obfuscate the value of items being purchased and drive up revenues in a shady way.
By the way, your "news flash" of Frontier being a business is old news. Everyone knows they're not running a charity.
For those of you with an open mind, here is an interesting article that goes over many of the facts and figures surrounding in-game currencies (among other gaming economic system studies) and why they exist in gaming today.
