I guess it's never too late for a start. and ofcourse we can't possibly connect every major city, considering we live in an archipelago. but "real highways"/expressways/freeways can be built on each major island, not necessarily to connect all major cities at first. but atleast something close to that. then a network of such highways might be implemented afterwards to really connect all major cities.
for starters "solidifying" the so-called Luzon loop and turning it to a "real highway" would be nice.
