"How could it not be?"

It is preposterous to suppose a sole individual constructing such a facility alone, on their own dime. This is a straw man argument.

Corporations do this kind of construction, and they demonstrably and unfairly gain such resources despite other's use of them routinely, and characteristically.

"If he digs a well and draws water from it, who else is owner of that water?"

That water is part of a water table, which isn't separate from the water in the surrounding area. Various communities try to regulate this commons, and are routinely and characteristically corrupted by corporations to favor them.

"... if people rely on the water from his well as there is no other source of water there, then they still do not have the right to steal from him this water if they otherwise die. It is his water by right of appropriation..."

This is preposterous as well. What prevents me from appropriating the air you need to breathe, then? If I build a box around you, and prevent air from being exchanged within it, according to you I have done nothing wrong.

That is exactly the same argument as someone digging a well that then deprives others' use of water in other parts of the water table - and this is the extant state of government.
