1. Separation of powers
2. Accountability via body-cams
3. Freedom of speech to protect political progress that threatens incumbents
4. Making voting systems that have auditibility
etc. These are all good practical ways to reduce trust in government with no downside. Why ask for "trust" instead of offering proof?
It is our role in a democracy not to trust our government, but to guide it (by selecting the correct representatives) to represent us on the things we agree on.
