Just to play devils advocate here.
There's a threshold where a particular hobby becomes inaccessible at the entry level for all but the very few (read: elite).
The best example I can think of off the top of my head is custom PC modding. When over clocking 300MHz Celery's were still the rage, it was still possible for the average Joe to make a trip down to The Home Depot, grab some copper tubing, fittings, acrylic, some enamel, carve out their case, and put together a very decent looking case mod. As the art became more refined, obtaining customized parts became ever easier and the PC mod quality radically improved. It wasn't long before some of the PC mods became stunning works of art. The Half-Life Strider PC will forever stay on my wish list. All of a sudden, those of us who were part of the original group who forged new ground (can't say my Badtz Maru case mod is new ground

) found themselves in a hobby surrounded by ridiculously high priced aftermarket kits that were considered must-haves or case mods that only art students could accomplish.
When the parts and tools cost of a "basic" water cooled PC exceeded the price of the high end PC components itself and anything less was not considered worthy of attention, the hobby became inaccessible to most people.
There's nothing wrong with improvements in a particular hobby. The improvements I've seen in a vast number of hobbies are just outright stunning. Electronics, robotics, scale modeling, Personal Computing, etc. There are things available now that I only dreamed of ten or fifteen years ago. Many of these improvements and innovations are drawing my attention to hobbies I haven't visited in years.
Just don't forget to encourage those people who aren't able to afford the products from GGG or Ultimarc or wherever and are left to hack apart those keyboard and joystick controller boards or making their own arcade controls with bits of wood, PVC, VCR parts and glue.
