"things you are just not going to amortize in the same way as a large factory" True, yet if you amortize the cost of a single use router bit by hour, it is still a very cheap hobby compared to console/computer gaming or golf or other hobbies. Before ebay, every carpenter had at least one router bit rolling around in the back of some cabinet that cost $50 and was only used once. After ebay, we still have that same bit rolling around in the cabinet, we just feel guilty we haven't gotten around to selling it on ebay yet. A lot of people feel worse about selling something for 20% of purchase price than they would about buying something during a 20% sale which is an interesting aspect that crosses into all technical / capitalistic type hobbies. (capitalistic as in its all about investing money in tools to minimize labor costs to produce something, not a weird analogy with VC funds or derivatives markets)
