Why replace ACA completely? Do you think your replacement will be flawless? Otherwise, since ACA mostly works well (except for state govt and hospital roadblocks and monkey wrenches) why not just fix what can be improved? Do you realize how costly it's going to be to rollout a whole new system? I think you need your head examined if you think you can affordably replace ACA with something that's flawless and covers everyone at less cost to users - good thing you have health insurance through your job. Hope you're ready to lose your job next election if you advocate to repeal ACA.
