I think the intent should be that if an emergency situation arises, the president can act right away, but then Congress can move in to stop it (assuming they have the right amount of votes). This would encourage quick, sensible reactions to emergencies. In theory, the congressional oversight provisions would prevent foolish and/or authoritarian political uses.
The philosophy is that things take so long to get through the swamp of Congress (including all pork barrel tribute). Sometimes, in an emergency, it is better just to the let the President do it and let Congress undo it if it is that controversial. The problem here is that Congress currently needs a veto-proof majority. That part makes it problematic. If this is for convenience on relatively uncontroversial emergency matters, then requiring a veto-proof majority defeats the purpose of limiting it to non-controversial matters.
