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.

All right, so I read up the whole up and this is what I have to say:
BWHAHAHAHAHAHAHAHAHAHAHAHA
It startet off with some story that you later labeled as:
[...] example of free market failing [...]
The other guy just bought it without questioning what exactly was the the market failure there (spoilers: there wasn't. macs suck not because of intel or microsoft, stupid macfag troofer. gb2bed steve jobs) and goes on about something completely irrelevant because he doesn't know enough about libertarianism.
From there it goes:
you: YOU'RE STUPID! (+every odd post) END OF DISCUSSION!
he: NO YOUR STOOPID!
For doing this for about 2 months both of you deserve the title "Master of Stuidity".
