That's not the point. The comment implies all it would take to "house the poor" is to spend $100 billion. The government spends that amount many times over. Spending $100 billion is not a big deal. If that were sufficient to end homelessness, it would be done already.
Also, since when is confiscating 100% of someone's wealth, "paying their fair debt"? Do you happen to have any personal wealth? If so, why haven't you donated it to the government yet, as fairness dictates?
