As far as lunches go, I can and do get them cheaply by buying materials and making them myself.
I'm not talking about ordinary home-cooked meals, but tasty restaurant meals created by expert cooks. I'm willing to pay the cook for the ingredients + hourly wage + rent of his kitchen tools/or he can borrow my kitchen utensils.
My condition: the restaurant open sources all its recipes, so no we don't pay for any trade-secret IP.
Adding up these costs results in 1/5th the cost we pay at restaurants. Why should we pay so much for the IP and renting a table/chair for an hour or so?
No cost to anybody else involved. No noticeable use of scarce labor or materials.
But I specifically selected examples where labor or materials are not scarce. Cooking is thousands of years old, and cars, hundreds of years old. If I were to pay for all the materials and labor required to build cars, or prepare food the cost would be a tiny fraction of what we pay in retail. Why should we pay so much for non-digital IP? If you agree to apply the same low cost to physical products (which are simply, IP + raw materials), we can agree to reduce the cost of digital goods.
Why do you care about how a product is embodied: physical or digital? It requires the same cost structure (maybe more upfront costs than physical products), talent and genius to create both types of products. So why should you have the right to pay little for digital goods?
