I see your point. But I still think the perverse incentives exist. Once you have customers, you deviate from your mission. Right now the US postal service is largest customer is bulk mail, spam. They're basically stuck in regulatory capture now. They can't do things to reduce unwanted spam, they can't offer services to people to not deliver bulk mail. Because their largest customer is bulk mailers. The people receiving the mail aren't their customers anymore. They're the product.

I forget the name of the company exactly I think it was inbox, they were working in San Francisco, they would go to the post office and receive the mail for individuals then scan the mail and send it to people digitally. Basically it was the postal service but no physical delivery. They had a pilot program going, but then the bulk mailers got wind of it, and used pressure to shut it down. So innovation that's available I think in Finland or Sweden is not a possible in the US due to regulatory capture.
