I'm no Mac user but the value of a Mac to its users has more to do with its seamless integration with all other Apple products and services rather than a purely utilitarian perspective in raw specs/performance per dollar.
This has no value to me as their pricing is out of my budget and I don't like the idea of being locked into a proprietary ecosystem, which is of course down to everyone's personal preference, but judging by sales numbers, it looks like Apple's ecosystem has gotten some things really on point.
Most PCs do at this point, also that secure enclave is very rarely both effective and something empowering the user so it's often ignored outside of very closed systems like Macs and phones.
I’m not sure what dimensions you are considering 2x the specs, but Mac laptops with an m1 beat any PC laptop on CPU performance, battery life and heat output.
Yeah, you can get a PC with more ram, more storage and a bigger GPU.
Specs like GHz doesn't really paint the whole picture. In any case, M1 is a whole other story, and Apple went from simply being better to being a decade ahead.
Raw speed isn't everything. They are offering performance per watt, per weight, and per battery life metrics that are unavailable anywhere else. Add in display, camera, security and hardware accelerated machine learning capabilities, and there are many, many axes on which they offer unique capabilities.
