No, correct. It's called -infinity distribution- and is a -requirement-
for RNG's to be accepted as such.

No, that-s 1-distributed, not infinity-distributed. There are many
k-distributions. This guarangees the -largest- string that will repeat.
Clearly you can't have even a PRNG in this case.
If you have i characters and want a sequence of length greater than i then
clearly 1-distributions must be allowed.
Read Knuth, and quite arguing just to argue.
