Yes, in my state anyway, most rural people are rich.
All land ownership is a piece of paper with lines and angles drawn on it. The landowner does NOT own the air that blows across it, the water that flows across or percolates into and under it, the wildlife that wanders across it, and numerous other things valuable to the greater community.
You comment on collecting water in rain barrels is disingenuous and shows that you are scientifically illiterate too - you apparently have never heard of the hydrologic cycle? Collecting water in rain barrels has considerable environmental and social benefit - especially in urban areas where it reduced stormwater runoff and associated dangerous urban flooding and non-point-source pollution. if it used widely enough, it would even provide summer groundwater recharge and low-flow stream augmentation and improve water supply reliability. In many urban areas it should be mandatory with the barrels provided by the government. But yes, because you don't won the water that falls from the sky - it is a common resource owned by all - should the laws of physics magically change and the water collected in a rain barrel vanished from existence forever, or the rainwater was unavoidably polluted in the process, then of course rain barrel water collection would need to be restricted.
I really think you are on the wrong forum here. let me suggest "Reason" or "Free Republic".
