> I don't care about marketing and branding, and focus only on the product itself.

That's where I find your framework breaks down. You can't ignore marketing and branding. Apple, Tesla, countless companies would be nothing without strong marketing and branding.

A product is nothing if it doesn't reach consumers. A similar point was made upthread that pricing de facto segments your market. You can set the price to whatever you think is best. If you aren't reaching the right people or have trust issues with your brand, ex. a new, untrusted product, then no one will buy your product no matter how many features it has.
