To simplify what I had here before (and make it hopefully less argumenative):
What system would be verifiable and trustworthy? How would that differ from what we have now?
And I'm still not sure why you continue to make that the issue. It's not so much argumentative as it is odd.
In any event, what I did point out are some of the underlying issues that make the current system corruptable (i.e. untrustworthy). I don't really feel like retyping that, so if you're earnestly interested, perhaps you can check my ancestor comment on this thread.
As far as devising "practical" solutions, surely identifying and addressing those core issues might be a starting place.
EDIT: But perhaps the real question is: what exactly is your point?
