Regardless of all the accusations of incompetent, unfair, or inconsistent enforcement of their own policies (which are serious and deserve inspection and criticsm), I don't think Wikipedia's stated policies around notability are unreasonable. The policy that most directly addresses your comments is "Wikipedia is not an indiscriminate collection of information": https://en.wikipedia.org/wiki/Wikipedia:What_Wikipedia_is_no.... They explicitly reject arguments of the form "we should be able to have any page we want as long as storage costs aren't a problem."
