Taking the unearned is not freedom. It is the violation of individual rights, and is necessarily opposed to freedom.

Besides the indefensible moral issue of theft, services like bittorrent - when used to steal property - help inflate the same sort of economic bubbles that we have seen (and increasingly will see) bursting, by creating artificial demand that would not exist in a free market that upholds and protects property rights. As one example, a software company suddenly inundated with support calls/emails/forum posts from thieves using their software, is forced to either a) hire more support staff, or b) lock down their support services. In either case, wealth is malinvested and user experience degraded.

Do not want for that which you cannot or will not voluntarily trade.
