"From each according to his ability, to each according to his need" is a fundamentally good idea.

Reasons to disagree

1. On the surface this sounds good. This is why young people gravitate to liberalism. However when they get older, they realize that liberalism has negative un-intended consequences. For instance, how does one go about implementing the "to each according to his needs" part? To give something to someone according to their needs, you have to have it in the first place. Or steal it. And you don't want to trust a government that has the power to take everything from someone. Power corrupts and ultimate power corrupts ultimately. And then you see a sinister lining to the "from each according to his ability".
2. Shouldn't it be "from each according to their free will and energy"? You can drive a horse till it dies, or until it does not have the ability to go any further. Is that the way a government should look at it's citizens? What if I have the ability to be a great architect, but I don't have the motivation? Should the government force me?
3. The free market leads to better quality.
