Central / trusted / private issues are fine. Provided they're not enforced by the boot of a state, and alternative issues exist in an open market. Given those conditions, such currencies may end up serving only fools, traders, niche, etc. See also: The ICO's of essentially nothing more than renamed regen'd bitcoind... as to ever becoming a major currency, they're pointless.

But the thin edge of the wedge of statutes is very, very pleased with centralized solutions ... yesss, thanks you very, thanks you muchhhhh

All your rights are statutorily the oligarchs thanx u very much.

Whilst you the individual are bound by statute to not use gold and silver coin to trade and exchange services, under pain of statutory punishment, no DC shall provide a superior alternative - only tech rainbows to inspire the digerati. The thin edge of the statutory wedge began many years ago when The All Powerful United States legislated with rainbow statutes declaring The iNternet a tax-free haven - and renewed their statutes, and renewed them some more. And people thought it was good. But the truth is, the goodliness that people thought it was, was merely entrainment, brainwashing the people to be entrained into the authority of statute and therefore the externalisation of your individual sovereignty and therefore subservience to the superior external authorities - the banks, govt, oligarchs.

Here, let me fix the name for them http-hashcash should actually be http-scamcash http-jewcash

You're welcome.
Summary of critical design "flaws" appreciated. Externalisation of authority strikes again - or rather in this case the "intent to cause the pleoble to externalise their authority".

Screenshots, FAQ, and executables for some platforms are at:
The problem is that you have to trust the issuer to not defect, and to not be forced to defect by the cops. It is completely centralized, which means the state can apply pressure - the cops come and seize the issuers reserves, or seize the issuer himself and his computer. This is the problem that decentralized currencies like bitcoin seek to avoid. Unfortunately, decentralization raises transaction costs, which are becoming extremely burdensome on bitcoin, resulting in spontaneous recentralization.
