There's nothing in this bike that makes it reasonable to price it like a small car.
I love biking but 8 grand is just taking the Mickey.
On the other hand an $8000 bike, while it may work just fine for OP, is absolutely insane for most people out there. You can get the same functionality out of a <$2000 bike. Regardless, the way OP is using it is neither safe, not legal. I hope it was done just for the photo op and some Twitter likes but I would hate to be around that bike when one of those chairs fall off, or a gust of wind catches the payload like a sail, or simply ride past it and be forced to move further into the traffic or pedestrian lanes to go around Oversized Load here...
Love your ride so much you want to display it in the living room? Can't do that with a car :-D
You've clearly never seen houses of millionaires.
And anyway, I like my bike but since it's always full of dust from the streets or brake pads and even worse when it's raining why would I bring it in the living room, that's just crazy. My bike is tool to get me from A to B, not a hobby to spend my time tinkering with or cleaning every day.
