Well then the economy of a government fall down if it is without taxes. Because if all transaction would eventually go to bitcoin, then their will be no money for the government and it will go to businessmen or corporation. That would mean big conglemerate is getting richer while the government itself is just stuck. Unless the government would make services with bitcoin, then it is really hard for the economy to increase without taxes.
Opposite. The big conglomerates would become weaker and smaller/go out of business if governments got weaker or smaller.
Governments together with big banks protect the big congomerates and basically feed an anti-competitive environment especially as regulations are introduced. The biggest and richest can easily comply with any such regulations and also can afford to pay for sponsoring to make more regulations to stave off competition.
