Area Code Games are heavily scouted, by colleges and pros alike.
Travel ball became the chief recruiting venue provider largely because the reality is that baseball is often the red-headed stepchild of a college's athletics department. First comes football, then basketball, then Title IX, and then we see if there are any moneys left for other sports. Happily many programs have, in recent years, been able to achieve funding levels previously only dreamed of. But saving money on scouting players is essential.
Not to mention, as you can imagine, a college coach is not always available to roam town to town taking in one game at a time, even if money weren't a factor. He has his own team to run daily during the spring, not to mention a family he'd like to get home to. To do what you would suggest would require a tremendous expansion of the number of funded assistant coaching positions.
It does no good to cry over things that are not going to change. If you want to get recruited, you know the landscape. Either do what you need to do to put yourself out there, or risk getting passed over. Players are not going to learn any younger that you have to pursue opportunities to get them. The parallels to seeking a job are apt, because in many ways, that's exactly what a player is doing.
