Vote negative -- The design of the tax determines the quality of debates – without it the affirmative can no link any argument in the 2AC

Simply put, the carbon tax is a shell game. The range of designs, prices, rationales, and claimed benefits varies so widely — even within many individual arguments for the tax — that assessing the actual validity of most discrete proposals becomes nearly impossible. The insubstantial effect on emissions gets obscured by discussions of the fiscal benefits. The negative fiscal effects get offset by claims of environmental efficacy. The tax's simplicity and practicality are touted, even as new complexity is introduced to address each flaw. The same revenues are rhetorically spent to achieve multiple ends, even as the different promises made to each constituency would be rejected by the others.
