Honestly, the only way I can see TVP really take off is if there was a collusion between TVP & the US military along with a few other major militaries around the world.
TVP would need to promise the military industrial complex that they would effectively have a far bigger resource budget then current system would provide with the primary resource being man power to run the military industrial complex.
There would be a Coup d'etat between the militaries and all major powerful governments that would install a new unified government and the new system.
There would be alot of panic, probably alot of deaths, but in the end, it would be a better system as people would realize how good life would become.
Then there will be negotiations between this new government and other governments on converting.
There will be some resistance, and a few more wars.
Conquering would happen, and eventually a 1 world government.
Then TVP would truly happen.
