They can charge that but I imagine they're not making a lot of sales. I saw someone selling pretty basic chibis for 3000-6000 bucks yesterday and wondered if they'd actually sold any units.
That said, prices have increased in the past few years because vtubing has blown up to the degree that it has. Most of the models for sale you see are also being sold to vtubers. vtubers generally have very little technical knowledge and see it as a business expense so they can start making money.
