Slave labour?

According to Robert Nozick, income taxes are (on a par with) forced labour, since a portion of someone's work time is spent working for the benefit of others.

Now John Lydon - a.k.a. Johnny Rotten of the Sex Pistols - has gone a step further. He claims that an agreement between band members that allows a majority of them to licence is like slave labour.

I'm not sure exactly how this claim is supposed to stand up. He's not being forced to work, even if the results of his former work are being used in ways that he disagrees with.

In any case, it's interesting - from a decision theory perspective - to see him objecting to majority rule and insisting that agreements ought to be unanimous.

A unanimity rule would also give each band member equal power in the abstract. However, it is non-neutral, in that it favours non-licensing over licensing, which may be more in accordance with the preferences of some members than others.
