I disagree with your claim that all examples involve coercion, but I guess it depends on the scale on which you require to be considered a success.
The reasons why are numerous, in addition to all the benefits of anarchism (which you have to be for in the first place before you can support libertarian socialism, if you don't then this discussion is mostly meaningless) you would have the benefits of even more liberty and power distributed among a strong community, with less poverty as well. Income inequality is bad for markets and hurts everyone, and is a huge factor in crime and happiness. There is much more incentive for workers to be involved and work harder in their workplace if they receive shares of the profits and not just a fixed wage. You claim that most people just want to be workers, but why would they not want to make more money for themselves that their own labor has contributed to? Why would they not want to have a say in the decisions that directly involve their own economic outcome?
I think what you meant to say there was income inequality, and I've taken the liberty of fixing it.
Aside from that, I agree, in principle, that people will probably have more incentive to do a better job if they have a direct stake in the success or failure of a venture. Not all businesses lend themselves easily to that model, though, and sometimes decisions can't be made by committee. I would argue, as well, that income equality, everyone making the same amount of money no matter what they do, would do much more harm than good.
If you haven't read it,
Pictures of the Socialistic Future, by Eugene Richter paints an eerily accurate picture of what happened in Russia and East Germany under socialism. What makes it so disturbing is that it was written in 1893.
One of the principle problems was wage equality. Without premiums placed on high demand work, that work went wanting. The fact that the workers all got the same amount whether they busted their ass, or just did the bare minimum didn't help either.
Wage equality might work well in each individual shop, provided it was something like profit sharing. Service oriented jobs, such as waitressing, will
not work well with wage equality, however. Historically, as soon as a restaurant started sharing tips, service in that restaurant went rapidly downhill. I've watched it happen.
How an individual business decides to disperse its profits is no real concern of mine, but if I get poor service, or a poor product, I will not be returning to that business. For some businesses, the coop or profit sharing method may work. In fact, it may be the best option. For others, it will surely doom that venture to failure.
In short, the market needs income inequality, as not all work is of the same value. In addition, an increase in income should be the result of your own effort, not that of your fellows'. And if equal rewards for unequal effort causes the effort to seek the lowest common denominator, things will not work well.
