There are alternative models, and interest marketing is interesting for that, but it depends who controls the process.
Lately I had to buy a dining room table and I had to go through 32 stores before finding the right one. I would have liked to make a tender. Those models are being developed, where I could make that tender. I want a table that seats a certain number of people, and so on and so forth. I put it on a site without any information about me. I'm a buyer. When the right seller comes in, I will contact him. Don't call me; I'll call you.
Those models are possible, so that's why we must not impede those kinds of innovations. We must look forward in that direction. We could develop models that would be economically sound based on that. There are alternative models.
