"strives to regulate every aspect of public and private life"
Not so easily today. Sometime totalitarianism can have a degree of economical laissez-faire - of course as long as you're on the government side (and bribe them enough), just look at China or Russia. Often they explicitly don't regulate what other democratic countries believes needs regulation (monopolies, workers' rights, pollution, IP, etc:) because it would bound the power of the oligarchies.
Marxist totalitarianism, and their obsession for regulations because of the ideals of a new society, are just a kind of totalitarianism - other kinds exist - less idealist, maybe, more mafia-like probably, but not less dangerous.
