“Giving tzedoka is a PRIVATE thing and NOT a govt thing.”
I’m not sure if you are new to Judaism, or if our galus has been so long that you have adopted foreing ideas.
In Judiam there is no such distiction. When moshiach comes and Jeish leadership iis reestablished the government will force you to pay maaser, with force if neccesary (kofin al mitzvas asei) they will force you to leave your field fallow every 7th year .
See if you learn Navi you would know this, (for example Yosheyahu sent soldiers to ensure that avoda Zara was eradicated)
