Ok I see this is getting deeper into "what is money" and "what is yours". Here I'll focus on "what is need?"
You say I need healthcare. But, ultimately, I might choose to jump off a cliff (some people do). I use that example to show that you telling me what I "need" (health) is really just your opinion. We're a part of a world full of animals which received no "health care" for a few billion years, so, did they need it? I think this is fundamentally what defines a statist: believing that you or this system knows what I and everyone need, and has the moral authority to use force to satisfy them.
You're so sure that you know what I need, you won't even accept at face value when I say "nah, that's a negative for me". It's not for you to decide how I feel about it. The downside to universal healthcare is one person saying "cuz I don't want it."
Or, do you believe the voices/opinions/feelings of individuals are not relevant here? If that's not how we determine upsides and downsides, what is?
If peoples opinions are irrelevant, if you know what I need, why not apply your universal ideology to everything? Why not decide who i need to marry, or how many kids to have. Sleep is essential to health, so, do I need a nap? How many minutes do I need? Surely sex is a human need! What line do I stand in for that? And when theres a shortage of providers, do I just take it from my neighbor, or directly from the government agent's wives?
Either I have the freedom to opt out of a system (meaning it's not universal), or I am oppressed by it, by definition. every tyrannical government since the dawn of time has claimed "this is what the people need, even if they don't know. And that stuff you thought was yours, belongs to us". And people justifiably fight back: "You do not own us, you do not represent us".
To summarize: your position is based on the false premise that you know or can know what everyone needs. But you can't know that, it is unknowable, and even if you could, it would be unethical to use force it distribute it.
