Just a couple of questions/observations.
I’m assuming(/hoping) you mean this in some economic or philosophical sense of the word force, but capitalism requires brutal force in order to operate. And not (just) through the criminal law/protection of personal property, but by the way that most of the commons are brought under capitalist(ic) rule. Violence is both the enforcement and aquiring measure that separates individuals from commonly shared resources.

You are correct in that for capitalism to work there needs to be fundamental ownership and property. Where that gets blurry is that none of us were born with anything at all, and also happen to be made of exclusively recycled and communal resources (carbon, microorganisms, water, etc…). The very idea of ownership in this communal world is not without problems because it requires the delineation of “yours” and “not yours” based on…
-(insert any systematic oppression here)
Humans (and every other organism on this planet) has shared resources to arrive at where we are (leaving aside any thoughts about if “where we are” is good or not). To simply say you (actually) own this/any land while honestly believing that (without a sense of transience or humor) requires a massive (historical) short-sightedness.
Now to a certain extent it is difficult to picture a world without property ownership. I can’t do it either. But that does not mean that the idea of property is immutable. (the very idea of free market capitalism is barely a blip on the human timeline)
I’m not sure how these two things (property vs individual) are anything at all related, other than if you extend anything an individual wants to be a conflatable parameter (which would have massive implications with regards to violence and theft, etc…).
The mechanism which drove this to be, is the for-profit nature of capitalism at work. This is the biggest flaw with the commonly held (mis)conception that capitalism seeks efficiency and an optimal state. Capitalism seeks profit, which one path of arriving at such has the occasional byproduct of creative efficiency, but that is not the purpose of capitalism. The U.S. healthcare system, as a result, is a great example of capitalism because it is producing a tremendous amount of profit. It is unfortunate that comes at the expense of human health and suffering, but nothing about capitalism seeks to minimize that (only if you consider the possible discouragement that ‘bad press’ may offer, but as time has shown, that is a really toothless mechanism).
