Pragmatic implementation is needed. We have enough theory.
Eliminate ATF. Eliminate all Fed sin taxes. Let states levy and collect them. Let states regulate them.
Eliminate FBI role in bank robbery. FBI is only involved due to ego of J Edgar Hoover 90 years ago.
Eliminate Fed Dept of Transportation and all Fed transportation and energy taxes. Interstate highways? Mission Accomplished. Only short connectors and a lot of maintenance yet to be done. State and local can do that better than the Feds.
Mass transit? The people who want it are concentrated in a few states. That makes it a state issue.
Airport landing and passenger fees? Let the states levy and collect them.
The main role of these at the federal level is for Presidents and Congressional Leadership to use the above to BRIBE Congress critters into supporting omnibus bills they would not otherwise support.
Remove this ability to BRIBE and the quality of other bills will improve.
Agree. It is time to reclaim our sovereignty through Article V.
