Yes precisely, this to me is the essence of anarchism. To have the free will to opt-out or opt-in to any voluntary exchange without coercion. To keep my factory floor if I like, and if people voluntarily want to buy enough widgets from me that I can build a space ship, that is great for everyone because I've given the world lots of value and they've voluntarily given it back to me in exchange for that value.

It's really strange to me that leftist anarchists and capitalist anarchist are such bitter enemies. I think both can survive under the banner of a system without coercion. Anarchist socialism is merely what happen when some group of people consent to each other to share their resources. Those that don't consent and want to use free trade instead look more like capitalists can continue to do so. Personally I pick the latter because I think it will bring me more prosperity, but I'm very live and let live and can see both ideologies living peacefully side by side so long as no one coercively tries to take the property of another.
