I'm sorry I just don't understand you logic. What you are saying is that I should buy a 2700X essentially even though I have zero interest in it.
Buying something because you want it is a thing and there is nothing wrong with it. I hope it's what most peoples decisions are based on. You are making far too much of this value crutch imho. Here's the thing, I don't need to justify it. That's the bottom line. I will though. If I have £600 to spend on an item and the item I want is £600 but there is another similar item that is £300 that I don't want to buy, I'll buy the £600 item. That's how it works. It's why someone may spend £1500 on a TV instead of a £1000 one that gives a similar experience. Or spend £100 on a kettle even though a £50 boils the water a bit slower but still boils it in the end. If you base your purchasing decisions on value then that's fine, other people don't.
So I have no interest in Ryzen, nor a 8700k for that matter, I already have 6/12. I don't know why except that it doesn't excite me, Threadripper does, not Ryzen. I'm not going to buy something I don't want just because and that's how it should be. We make our purchasing decisions on what excites us or at least I do. If you buy something you are interested in and have a passion for but the purchase is not made mostly on emotion I'd find another hobby.
You're deflecting for the most part here... we're not talking about a kettle or a TV, we're talking about a CPU (or we should be), which has a very specific set of functions and performance metrics which you don't seem interested in, instead choosing to imbue it with an EMOTIONAL response and nothing else. It's worrying that you don't see a problem with this.
You are solely focused on this 'want' and 'excitement' angle... as though that is the only criteria for buying anything. Really? You genuinely think we should all make purchasing decisions based on pure emotion and nothing else? That said, I don't disagree that this is what a lot of people do, and all speaks to the mess society is in regards mass consumerism, zombie culture, new shiny shiny and masses of debt, but still, it goes without saying that this is a serious problem and far from healthy. Your CPU purchasing decision isn't going to change any of this, but that's besides the point.
Along with many other people, you've simply fallen in to the trap that marketeers and advertisers have designed for you, and this is EXACTLY what they want you to feel. God forbid that you actually think about a purchase sensibly... they WANT you to buy on emotion. I'd say you were 'free' to do that, which you are of course, but freedom doesn't really come in to it given the manipulation.
Why is value a "crutch"? It doesn't need to be the ONLY consideration, but it shouldn't be thrown out the window solely in favour of emotional response! What's worse here is that you seem completely oblivious to what's going on, not even questioning why something like the 9900K "excites" you. You then compound that by saying you hope most people make purchasing decisions based on emotion. WHAT?! We're intelligent adults, not mindless childlike autmotons driven purely by our emotions!
