Why is libertarianism so infallible?

Libertarianism is the inclusion of every sapient being into the decision making process and all that logically follows from that. Utilitarianism is the objective of ensuring the most happiness for all sapient beings and all that logically follows from that. Sometimes they compliment each other, other times they contradict.

Repeating what you know wrong doesn't make it true, socialism and etatism are two completely different things as it has been repeated countless times and even though it is an obvious thing anyone should know even gallons of sources proving your delusions wrong were provided, yet you STILL keep repeating the same thing, I can't honestly believe in the existence of such a monumentally stupid and ignorant person. Additionally, the faults of libertarianism were discussed in the preceding thread, in which you replied to a similar manner - ignoring facts, repeating the bullshit someone made you memorize.
