I agree about the size. Especially for a sailboat, I would say smaller is better. I have more fun sailing a 12' Laser dingy than a 40' sailboat, simply because it is more responsive and you feel like you have more control.
And for sail and power boats alike, I don't think I would want to own a boat that I couldn't pilot myself or fit into most harbors. Otherwise it's basically a glorified floating luxury hotel and expensive status symbol.
He can pilot it himself. I think if you are going to have a mega yacht, sail is the way to go over power. Yeah, it's a floating home, but it can also sail - that's awesome. You can take a tender into harbors.
Also, longer sail boats can go faster than smaller ones, when you don't plane. So a bigger boat means you can travel faster over long distances.
He can take the helm or push some buttons to trim the sails when they're on open water, but I doubt Perkins is the guy navigating harbors and docking it. With a yacht that big it takes a professional. Their crew is 20 people!
And while I've certainly never been on the Maltese Falcon, with a boat that big it seems like there wouldn't be much difference between a motor yacht and sailing yacht, except the sailboat heals over a bit and you save a lot on fuel.
