As long as power is centralized into a few politicians hands, there will always be a massive concerted effort to buy that power.
Everyone who champions for more state-intervention, this is the natural side-effect you'll have to live with. Welcome to your unintended creation. Transparency is the only possibly counter-balance I could see helping the situation, but I don't see any level of transparency being added to gov operations. The trend has been in quite the opposite direction.
In my opinion the only real solution to government corruption is limits on government power.
My point here is that the system is locked down as long as money controls it. We cannot release state control over the economy until we get money out of politics.
The corruption goes both ways: politicians depend on donor money, but to get the donor money they have to create complex legislation to extort with.
There is a great story in Republic: Lost about Al Gore and early internet regulation where the senators essentially say: "If we leave this unregulated, how will we make money off these guys?"
From where we are now, we have to work to reduce the influence of money on politics before any other reform can be approached sensibly.

Whereas currently 86% of people in federal jail are there for victimless crimes:

Our political system cannot reach unbiased, good decisions about what types of voting systems to implement if it's being swayed by big donors.
We have to hack to get money out of politics, so that our politics don't get hacked!
Also, I'm really curious what sort of things you all think you can "hack" that will really make people more free. After this, will the NSA be gone? How about the entire military industrial complex and all it's mouthpieces on tv and in Congress? What about the drug war and the power of big pharma? Diebold? Dynasty families like the Bush's and Clintons? Etc Etc Etc.
If any of you were serious about freedom you would be figuring out how to hire lawyers, not coders. A better voting app is just an easier way for my representatives to give me false choices.
Some of the suggested hacks are listed at the link. They will not, by themselves, get rid of the NSA, but they are reasonable steps that the anti-corruption movement can take at this time to raise awareness and build momentum.
You can join in and start working on the BIG problems you listed, or you can say this cannot be done and do your own idea which seems to be about hiring lawyers.
