The market cannot compel people to purchase items with the threat of violence. For example, Apple cannot dictate that every American of a certain age must purchase an iPhone or face a fine and possible jail time. On that basis alone ObamaCare is not remotely capitalist.
When you purchase a car in certain states you are compelled to provide proof of insurance. When you purchase a home some states compel you to have homeowner insurance. Are neither of those market transactions "remotely capitalist"?
Nope
