All of those items are still available at MSRP. You may have to wait a few months to get them yes, but it's nothing like the GPU situation. It would be heralded as a huge win if the GPU situation was like Apple - you order a GPU at MSRP, and get it a few months later.
Again though, the PC as a 'high end experience' is talked about like it's running the same software as consoles, as if it's a high-end phone and you just choose the one you want vs a budget model and you're running the same software as them but just 'better'. It's not. It requires significant developer expertise to take advantage of what it can potentially offer (ray tracing, DLSS) and also the potential pitfalls due to its different architecture (shader stutter, anyone?) - if publishers deem it worthy enough to port at all.
The notion that people will pay whatever they need to pay to have a 'high end' experience is bizarre, there's diminishing returns with the benefits of this experience as it stands due to process shrinks becoming far more spread out over time, requiring more custom approaches to realize the benefits rather than just brute-force (hence complaints about lack of DLSS support if a port ships without it). There is no market on the planet which does not flex or shrink with respect to the capital investment required to participate in it, I don't know why PC gaming would be any different.
