there is no such thing as free healthcare, someone has to pay for it...

Do you think it is likely that the person you're replying to doesn't know this or are they simply calling attention to the fact that Medicaid recipients receive care that they themselves do not pay for?

Is the statement in some way unclear? Care to suggest a rephrasing?

I'm fairly confident that the person I'm replying to knows this.

A better phrasing would be "subsidized healthcare".

I wonder if we get to the point where you are the product.

Not any more [1]. The Trump administration has sufficiently weakened ACA that you can now get insurance that isn't sufficient to prevent you from getting a huge bill if you have the temerity to have a heart attack or something else expensive like that.

Or you might not even have insurance, since they also killed the tax penalty for not having insurance.
