Sorry, what? You said "those MSRP 4070 cards don't exist at all", I'm confused what you meant by that when there clearly are several models on Newegg at the advertised MSRP.
Yes, premium card models exist and have always existed, for people who want to pay extra to get a quieter cooler or another few % OC performance.
That's different from "MSRP is fake because those cards don't exist and nothing is available at MSRP".
10-series MSRP is an example of a fake MSRP - FE was priced above "MSRP" and all the partner cards slotted in above FE. 4070 Ti is nothing like that, you can go buy a 4070 Ti for MSRP if you want, they definitely exist, and will likely continue to exist.
I checked the listing for 4080s and there is, unsurprisingly, currently a model available for MSRP there as well. It's backordered until tuesday (a whole 36 hours!), but, I thought you said they never restock after the initial drop?

Like yes you're not wrong that partners would rather make the high-margin cards and they do everything in their power to avoid selling at MSRP, but, that's because they're profit-seeking middlemen with a stranglehold on the supply of a scarce resource, not because they can't afford to make cards at MSRP.
Just like Zotac and EVGA - PNY isn't losing money on those cards either. They may not like what they're making, they'd rather sell you a corvette than an econobox, but they're not losing money either. That part is not true and is as hyperbolic as your inventory claims: they still make money, they just don't make as much as they want.
Like yup absolutely the margin is worse on an Accord than a sports car. Agreed. The dealer still isn't losing money on the econobox at MSRP, no matter how much they wail and gnash about it, and it's not good for consumers to just increase the price so middlemen make a fat margin on basic-tier shit.
People generally look back on car dealers scalping Hondas in the 80s (and cars/trucks during the pandemic) as being a bad thing, but, somehow the board partners have gotten consumers into this idea that margins for middlemen are a good thing when it's GPUs.
