Keep in mind that when Bandon Dunes opened, you could play 36 holes for under $100 per round. The initial greens fees may have been $90??
With Bandon, the demand was great enough that the greens fees went up significantly over time.
In my opinion, the golf world needs both- well-designed, moderately priced courses, and great courses on very good land that may cost more- both because of some higher expenses in construction and because the demand is there.
