My guess is the product you want to buy is on offer, but not at the price you are willing to pay. Do It Yourself is the market solution for people who want something different than what is offered in the mass market. The internet has enabled truly insane levels of DIY capability. Capitalism is not a charity. Therefore people that want products that cannot be sold profitably in the mass market can make it themselves, or buy it from the hobbyist/enthusiast market.
