I do not understand this 'hobby' deal , I mean this is a business , this is not a hobby , if you are rich enough to consider this a hobby ,
People spend thousands modifying their cars. Cars which end up worth less than a standard car when they go to sell.
People spend thousands buying bicycles to ride along the road, when a £90 Chinese bike would do exactly the same thing.
Hobbies are all, without exception, a way of 'wasting' money. Because you go to work to earn money, so you can spend it. That's the point. If you didn't want to spend money, there'd be no point in going to work in the first place.
