You don't necessarily have to combine hobbies with profit motives or a commercial approach.
If you like going on cruises or going to the pub every night, you'll burn money without ever getting a penny back.
In this respect, I don't care if my Morgan 4/4 or my old Indian Chief drastically depreciates in value, riding, wrenching and owning is still just as much fun. I wouldn't sell either of them without a compelling reason anyway.
