I didn't say "income tax" or "federal tax". I asked for examples of economies that don't collect taxes but have been effective. Survival is one important aspect of "being effective". So, an example that has survived to the present day would be more relevant.
The reason why charities underfund public goods is because of the well-known free-rider problem. It's the same reason why cryptocurrencies need to collect transaction fees and reward miners and cannot rely on charitable miners. https://en.wikipedia.org/wiki/Free-rider_problem
The OP I responded to said income and sales tax. You're just copping out by saying that I've fulfilled the criteria laid out was somehow wrong. But even without taxes, a charity can exist.
I guess you think all dead men were failures, if survival to present day is your criteria.
The "frees-rider" problem applies to government programs, too.
But you're right, we can't just depend on charity. We need for profit enterprise too.
