You seem to think that utilities are monopolies (which is partly true in some cases, where they are granted such monopoly entitlements by a government), and they they don't have expenses. They're not at the bottom of the economy. They need to buy fuels, for example: so they spend money with the fuel companies. Well, the fuel company needs to buy ships, drills and whatnot, and pay its workers. They money comes back into the economy at some point. If electricity providing is such a lucrative business, then there will be an extremely competitive market for providing that service, and no one company is going to be able to charge silly fees because they will make themselves obsolete. It is only through a government granted monopoly that such companies are able to exist. Governments care that you pay your tax, but their ability to enforce their tax collection relies on violence, and ability to prove the taxes need paying. Bitcoin creates an economy where the latter is more difficult, perhaps impractical with more private technologies. It might turn out that governments have to move to being more voluntary models of trade, else they might not be able to acquire enough taxes to fund their operations.
