A Simple Thought Experiment for Bordertarians

If I rob your safe and use the stolen money to buy crack, would you accept the crack in recompense or would you want your cash reimbursed? If the latter, why then is it you have no issue with immigrants except that the welfare state exists? How is it that the crack didn't belong to you - your stolen wealth did - but you feel entitled to say how money you view as stolen - taxes - should be spent and who should have access to those items and services?
