Ok, a couple things,

#1 , you can always find a rock at the right angle... I have 40 objects of different sizes and shapes with me in my bike bags. I can easily set up a platform for the camera to point a certain way. I might miss the occasional shot because I can't get the camera high enough (making a tripod worth it) but, overall, I'm not going to struggle to take the occasional long-exposure shot.

#2 . Timers can be frustrating. If I press the shutter and mess up the "stand" for the camera, then I've botched the shot. A remote weighs an ounce.

#3 . Saying that everything I've seen, a better photographer has already seen it or rejected it; I've never heard something so fundamentally incorrect. The composition, lighting, cloud formations, vegetation, human beings, etc. are infinite in variation. So infinite, it cannot be comprehended. Beautiful and breathtaking shots have yet to be discovered and will continue to exist for centuries, no matter where you go. People take pictures of the Eiffel Tower and win photo competitions even today, because an artist can always find a new interpretation.
