This makes alot of sense. I used to want to "complete" the loop just so that I could see it running continuously. After a while it gets quite mundane. Being a blue track (Plarail) collector myself, achieving a complete loop is much more enjoyable on plarail. IMO Lego Trains are a slow burn, the goal is not to complete the loop but to just make some sense out of the entire train travel/route.
Of course, if you have an extremely large room and a pile of cash to splurge, then you could just zone up over 80++ baseplates and make a damn good looking town with factories, residential etc.
