All new systems are introduced by force, even capitalism. Do you think that at one point in the past everybody in Britain decided that the state should be capitalist and so everyone, on their own accord, moved from communal land so it can be passed in to private hands?
And my original comment clearly shows that capitalism also had to be imposed for what once was communal needed to be confiscated in order to be redistributed.

Indeed, a state capitalist society transitioned to market capitalism. Nothing needed to be taken from any one person but the state. Not really a new system, just new owners.
That is correct, and I was pointing out that it isn't specific to communism: any government or economic system will have at least 1 person who doesn't like it, but the system being created nonetheless requires imposing it by force, and maintaining it by force, which nearly every government does to this day.
Since we're already knee-deep in nitpicking terminology, this is describing the general philosophy of anarchism, not capitalism.
Also, what is natural in me owning a factory on the other side of the world when I never left the city I live in?
The only societies where communism works without authoritarianism are communes like the Longo Maï where people come by choice, not by force.
