"We"?

Actually, exactly the opposite. From the introduction of RFC 819:

  "The intent is that the Internet names be used to form a
   tree-structured administrative dependent, rather than a strictly
   topology dependent, hierarchy."

Until that time, Internet names were indeed dependent upon "the then existing data networks" ("strictly topology dependent" hierarchy). What became the DNS broke from that approach to create a "tree-structure administrative dependent" with a "universal reference point" (described in section 3 of RFC 819).

Err, what?

The DNS "supports" an infinite number of roots (and, in fact, anyone who implements "split DNS" implements their own root), however people have found that having a single consistent namespace is the most useful for interoperability across administrative domains.  No idea where you came up with 35,635.
