No it isn’t.
There was a time religious institutions took care of the poor, and they did it just as well.
The purpose of government involvement in charity is to buy votes and curry favor.
What is your solution for the disabled if those institutions cannot support them and too few people donate?
Gas chambers? Execution vans? I suppose those are too much government as well. Just let the disabled suffer and die in the street. Then let the free market sort out what to do with their diseased bodies...
