Dumb hobbyist buys equipment to satisfy his hobby needs. Take pictures and enjoy. Business arguments are totally irrelevant as he does not use the equipment to run a successful business. Photography is a hobby so why would it matter to him if the value depreciates.
In terms of losing money I lose much more value with my other hobby. Being a computer geek... I spent 6k on a computer system with 3 screens and water cooling last year... In 1 year it would be worth 2-3k so a loss of 3k ... But do I care... no way its was so much fun building the system I would do it again in a few years
