I agree with most of what you posted. However, this statement sounds innocuous but is really very dangerous: "Healthcare should be a human right, not a privilege few can afford"
On the one hand, yes, absolutely everyone needs healthcare. It is essential for survival, and therefore, everyone has an incentive to build a society where it is readily available.
On the other hand, healthcare comes at a cost of labor. Many, many, MANY people across many different industries must labor at full time jobs in order for there to be health care of any acceptable quality level. And, those people are not anyone's slaves.
This is why one must pay for healthcare. One must "give back" to those who provide it, because those providers are not slaves; they do not and cannot work for free.
That is my issue with the phrase "should be a human right," as it implies entitlement. It implies that one is entitled to the labor of others, for free, which is never true.
Of course, you didn't advocate for slavery. I am just calling out the slippery slope there in your phrasing. I think it is fine for people to decide (via democratic process) that they would like to pay for healthcare through taxation instead of paying it directly on an as-needed basis. I also think that having some governmental regulation over the industry is an outright necessity, whether or not it is paid for via taxation. But the reason why healthcare should be paid for by taxation is because the country's free voters have chosen that funding model over the alternatives, not because of some sense of entitlement to the labor that others provide.
