The parts that are inaccessible right now seem incredibly easy to overcome.

Using a CLI-based tool is inaccessible for most people... but building a GUI around this would be very easy. I'm too lazy to google it, but I would bet someone already has a GUI, or is working on one.

12GB of VRAM may not be accessible on most computers, but there's nothing innovative about offloading that task to an EC2 instance. It just requires an opportunistic developer to tie the pieces together.

I would be monumentally surprised if Figma/Canva/InVision/Adobe are not already working on this.
