The reason we don't have to wait long now is because there are millions of people who aren't going to the doctor even though they should be. That is worse in my opinion than everyone having to wait for checkups, non lifethreating procedures, etc. The solution is to bring down costs and make it easier to train doctors, not to reduce access to healthcare.
Yes a major medical plan is affordable for many people but not so much for others. First of all you are quoting a pretty optimal scenario (relatively healthy, young, individual as opposed to older, less healthy, family). The fact is that advertised plans on ehealthsurance.com or similar sites are often not the real cost once the application process is complete and they account for even the most minor health issues. Once you get coverage, that's just the start of your medical payments, not the end. Further, it is only as cheap as it is because people with significant health issues are disqualified from the get go.
I agree that Obamacare doesn't do anything for cost. The big win from Obamacare is that preexisting conditions can't be denied. The mandate is an unfortunate necessity (otherwise everyone would sign up for insurance only after getting sick). For that reason alone I am happy Obamacare was passed. Now we need to focus on bringing costs down.
