the hobby paradox

if a guy has a hobby 

such as aquariums with fishes 

then that guy could buy a big aquarium 

and buy exotic fishes 

and make it amazing 

but only he and his friends will be able to enjoy watching the fishes 

and if he goes travelling on holiday 

then he needs someone to feed his fishes 

if a café wants an aquarium 

then the café personel needs to learn about aquariums 

and the aquarium is probably going to be very basic 

if a cultural house wants an aquarium 

then the personel needs to learn about aquariums 

and the aquarium is probably going to be very basic 

the hobby guy could of course start a company 

that rents out big aquariums with exotic fishes 

to cafés, cultural houses and so on 

but would those customers be willing to pay 

for what it costs to take care of big aquariums with exotic fishes 

the fact that few public places have big aquariums with exotic fishes 

indicates that the market is not willing to pay what it costs 

so the café has a very basic aquarium or no aquarium 

and the guy has a big aquarium with exotic fishes 

that only his friends are able to watch
