The most important thing a government can do for its people is adopt healthcare policy that ensures equal access to healthcare for all of its citizens. Healthcare is the only thing that is non-negotiable. Everything else is negotiable.
Health insurance is a simple, overtly socialist concept. A large group of people shares the cost for healthcare for the whole group so that no individual is overburdened by those costs. It is, essentially, systemic altruism.
The American Health Care Act denies certain people the opportunity to participate in sharing their healthcare costs. It is a policy that fails at the most basic levels of decency and conceptual rigor. It represents the prioritization of political ideology over the health and well-being of fellow citizens. Obamacare is definitely not perfect, but it only needs to be improved, not replaced.
