You really think healthcare isn't a public good? It's not. That a healthy population isn't a more productive population? No evidence of that, especially since those who get the subsidies likely are unemployed or aren't contributing much production to begin with. That accessible and affordable healthcare for everyone will end up costing everyone less? Subsidies don't magically pay for themselves. While a small amount of publicly provided medical procedures have a positive ROI (like vaccinations) the vast majority will not.
And you really do believe that repealing the ACA is going to result in your taxes not being spent on the "poors" who need but cannot afford health ins. or care? Really? It's not my taxes being spent on the poors via ACA but rather the higher premiums and goldplating my current insurance with coverages I'm guaranteed not to use simply to gain the premium costs to spend on someone else.
You obviously do not comprehend the fact that you already spend a good deal of your income for taxes that pay for indigent healtcare, although it's probably not represented as such in the income taxes, sales taxes, property taxes, et al, that you already pay. And your point is? That since I already spend a lot on medical care for poors that I should double down and pay even more with Obamacare or other redistribution schemes?
