In particular, you can only create a world where everyone is equal by taking away the freedom to not be equal.
Now, if we want to take away the "freedom" to be not equal on the downside, I'm not sure that I have much problem with that. If people aren't "free" to live in abject poverty, to have to choose between there medicines and their food, to not have air conditioning in summer or heat in winter... yeah, I don't have a problem with removing that "freedom".
But I have a problem with removing the freedom to be unequal on the upside. If I want to have more than you, and I can get it by producing more than you... why not? If I can't get rewarded for producing more, I probably won't produce more. That leaves less for everyone. Who does that help?
Thus those who try to prevent inequality on the upside remove freedom, and make everyone worse off. Worse off in two ways. First, society doesn't get the extra that some people would have been motivated to produce. And second, they made everyone less free.
Less free plus less stuff? Sure, sign me up... not.
