"Society" is not some autonomous external being that is free to do how it pleases. It is composed of individuals making decisions. If the decisions of the individuals are coerced, then the society's aggregate behavior is coerced.
Even if you could make that argument that coerced individual decisions could result in non-coerced societal decisions, you need to consider the entire implication: society is being "charitable" to itself, which isn't charity, it's selfishness. Charity is giving to others. So your point is nonsensical on multiple levels.
I invite you to not pay your taxes and watch what happens.
