Be careful what you wish for. Enforceability is something that keeps our tax rates low relative to other countries (we have one of the lowest tax burdens among developed countries, not that you'd know it if you pay attention to our politics).

If you want to see what happens when enforceability becomes uncertain, look at countries like Greece, which are the convergence point of the process that starts with the very wealthy being trivially able to escape taxation and proceeds, normalizing tax evasion by successively less wealthy cohorts of society, until virtually nobody pays their stated tax obligations, the government raises rates to make up for it, and the entire system becomes a joke.
