In terms of public acceptance, you're probably right. The Dutch in my experience love the old windmills, but modern wind turbines are in a different league in terms of harvesting the power of wind efficiently. Blade design is comparable to the aircraft wing design (seriously complex engineering).

In my post above I talked about seeing the Vestas V164 in person, but I've also been on top of the tallest wind turbine in NL (manufactured by Lagerwey). The higher the nacelle and the larger the rotor diameter equal more power generation (the higher you go the more wind you'll find), but public acceptance has a lot to do with things.

I've seen in person how the Dutch can lose their mind over wind projects, I was in Drenthe in 2014 at a public engagement night (where the public sees visualizations of the turbines, and learns how they can benefit and so on...). At Drenethe there were hundreds of locals protesting, cops, drama. Super scary. I was involved on the public acceptance side of things and have come face to face with countless thousands of scared and angry people. I can't imagine what selling a HUGE turbine for their backyard might be like, but going back to your original idea - selling a classic looking windmill would likely be very easy. The tradeoff is that classic windmill would likely generate a negligible amount of energy in comparison. But cool idea anyhow ;-)
