You love capitalism, but do you REALLY love capitalism?

This is all just based on a random thought I had...

You have most likely encountered people who have a self-proclaimed undying love for capitalism.

...That even their coffee mugs need to reiterate said undying love.

If a person says that he/she is a fan of capitalism, but does not believe that anarcho-capitalism will work, does this person actually like capitalism?

Now I understand that there are many forms of capitalism (unless you want to debate that), but anarcho-capitalism is practically capitalism  in its "purest" form.

I guess you could say that government involvement with capitalism (whether through the enforcement of private property rights or controlling the market) is what makes capitalism what it is.

What are your thoughts?
