The only thing I liked about Obama care was the pre-existing conditions clause.
You can't separate that clause from the mandate and minimum coverage clauses. All three were designed to keep costs from inflating on the one hand, and coverage becoming useless on the other. It's sort of like saying you like your lunch, but have a problem with having to pay for it.We can quibble about rates for men vs women, but unless you were matured to adulthood in a lab, it's hard to argue that men as a class do not benefit from improved and cheaper access to reproductive healthcare for women. (Also, better reproductive health means fewer criminals, if only because they're born healthier and with fewer mental handicaps.)
Opening up insurance across states would be nice theoretically, but you must realize that it's a states' rights issue for a large segment of the GOP, and a cause for concern among Democrats. It would necessarily limit and perhaps destroy the ability for states to meaningfully regulate insurance within their own borders. Unchecked, it would also mean a race to the bottom in terms of regulatory oversight as every provider would only sell insurance from states with the least restrictive regulations.
What state do you live in? Coverage in states like California and many other states that haven't fought tooth-and-nail has been fairly stable as far I know. The Kaiser HMO rate at my company actually decreased slightly for 2017, with no change in coverage. And California not only has a rigorous regulatory framework, it even maintains a weird tax on hospital income to pay for uninsured coverage.
Also, you don't need a federal law to support an inter-state insurance scheme. States could voluntarily permit policies to be sold from other states. For example, states in different regions could elect to normalize their regulatory schemes and open up their markets to each other. There's plenty of precedent for this. It doesn't require Congressional approval; just coordination among state legislatures like is so often done for other regulatory frameworks.
