Using a broad definition of theft merely serves to raise the noise floor. Your definition of "completely private" seems like "free markets" or "perfect competition": that is, things which are free from government interference only in misanthropic delusions. As Jefferson explained, stable ownership is not a natural concept; that you are considered to "own" things absent direct physical possession is a function of society. We also collectively agree to believe in this thing called 'money', which is also not an inherent property of mankind. That society can dictate rights and rules about property is inherent to the concept of each.
