Absolutely. There are certain niches where you really do need to focus on portability.
But like you said, a bike like this is extremely expensive, that's because a ton of budget is going into trying to counteract the main downsides of a folding bicycle: They're clunky, they're inconvenient, and they're heavy.
But for anyone who is able to sacrifice the floor/wall space, a standard bicycle will be lighter, and specc'd with higher quality components at the same price point.
