You are correct that many of us are closing our doors. You may not be aware that many of us have either done so or started considering an exit strategy long before Obamacare became law. Once the insurance companies took our money and our independence from us, there seems no reason to continue. Obamacare may continue the attrition, but I can say for absolutely certain, it is not the cause. The point here is that going back to the failed system pre-Obamacare won’t make a darned bit of difference in this regard.
