No. Although I could get behind a local tax initiative, like in a city, or county.
Either everything should be left to individual initiative and charity, and government always messes things up, or it doesn’t. Bringing in the issue of the particular size of the government jurisdiction seems to be confusing this question with an entirely different and unrelated subject.
Simply, gov't messes everything up and makes things worse for those it's trying to help, much worse. Any social program that is gov't run ends up a trap for those very people, and it always gets bigger and bigger.
As an example, before the ACA, 45,000 Americans a year were dying from easily treatable medical conditions because of lack of access to healthcare. Before Medicare, The elderly poor were either not getting any healthcare, or losing their entire life savings from unforeseen catastrophic medical illness in their retirement years. Somehow, voluntary charity was not doing the job. The vast majority of people would disagree that Medicare, despite not being perfect, has been a trap or that has not worked well. Even the most libertarian seniors on the program would agree, and would object to anything threatening to take it away from them. “ Stop socialized medicine and keep your government hands off my Medicare!“, right?
Here is one of the latest examples of how such a system was found to be necessary, and the success is created once it was implemented. With its new system of universal healthcare, Thailand not only dramatically improved its public health by almost every parameter, but, as an unexpected side effect, dramatically improved its economic growth as well.

If the community wants to help the orphans, they can do it voluntarily.
Back when there were no formal systems In place for them, most of them ended up on the street, exploited, and a big problem. Somehow, charity was never enough then. I’m not sure why you would think it would be any different now.
In your world view, it seems, saying you don't want to be forced to pay for someones insurance but trying to help otherwise is evil, but rioting and killing in order to force others to pay for insurance is good.
Charity is great. But it has never been enough. To say otherwise is to be ignorant of history. No, not everyone is a considerate gentleman when left free and alone to act as he wants. No, charity has never been enough. All developed nations in the world today have formal systems in place as a safety net for the basic protection of the basic human rights of their citizens- food, clean water, shelter, access to healthcare, and a basic education.
