Framework has been and likely always will be for the crowd that values repairability and reusability over any price/performance ratio. Being able to shove any GPU you could want (that's beem built for this) into that special slot is very neat, and pretty useful for the people who want to be able to upgrade their GPU separately from the rest of their system.

It's like getting the LEGO bricks from PC building into a laptop form factor - you can choose your IO, RAM and SSD, even your CPU. And now your choice of dedicated GPU. For a specific person, that's worth it.

If space is at a premium, or you routinely travel and wanna game, having a capable laptop that you can upgrade each individual part as needed becomes pretty darn tempting. If I had need for a laptop and had that routine travel thing, I'd honestly think about it myself. I could upgrade whatever part I want whenever I need to, and I can make old mainboards run home stuff or whatever. Turn an old one into a media player, or as a small PC for some other use.
