One can generate self-signed certs, paying 2 cents, but you can't generate
trust for such amount of money. Trust to public CAs can be measured by cost
of related risks and business, starting from hundreds of thousands dollars.

Such questions are pointless while cost of your data is less then cost of
trust to public CAs. Nobody wants to sign "rogue cert" for your 2 cents.
If you don't trust public CAs, use your own for peer-to-peer communication.
But you can't force other people to change their minds, leasing 2 cents.
