There are free options: the Intel XDK costs nothing. The Cordova CLI is free too, but is a more complicated setup.

Not necessarily: if development is 5x slower than it is now as we have to maintain 5 platforms separately, and due to the quirks of each platform each individual feature is only supported over a random selection of platforms making porting constantly a huge headache, and some features are entirely missing or incompatible with their browser equivalents, and some platforms face awkward bugs that others don't, then the end result is not necessarily even better than what we have now. None of this is hypothetical, other products on the market with this approach face these problems. If you add up all those other problems, is it really better? Then throw in the colossal engineering effort it takes to even get started on this...
It also won't necessarily remove the difficulty of configuring certificates, setting up provisioning profiles etc. All of that you still have to go through for native apps too, and that can be a big part of the pain of setting up mobile publishing.
I seriously wonder when the last time you used Intel XDK and third party plugins like cranberry's and witnessed the headaches?
