The answer is quite simple and is exactly the same as it is for Wikipedia: it's a wiki, and not everyone who contributes knows how to add references.

Why not insist that every piece of data added to wikidata is supported by a reliable source?
That's a genuine question. I don't know the answer.
Saying, "Well, Wikipedia is unreliable, too" doesn't answer the question.
You're all bright people, and I assume there is a good reason not to insist on reliable sourcing for all of Wikidata's claims. What is it, please?

Actually I think Wikidata is sourced more thoroughly than any single Wikipedia. Looking at the last chart in those stats, less than 10% of all items have zero sitelinks, and we can't see in the stats whether 100% of those have zero referenced statements, but I would assume that is not the case, especially since items with zero sitelinks and zero internal
Wikidata
links tend to be "cleaned up and deleted". At least one sitelink means
the
item is coming from a Wikipedia, and therefore the Wikipedia article will have references that could be used in the Wikidata item and just haven't been added yet. Of all the items with zero or just one statement, I
expect
a great deal of these to be linked to categories, disambiguation pages,
or
lists, as these types of items generally only contain one statement.
Also, we currently have no way to count unreferenced statements in Wikipedia articles, but there are very few Wikipedia articles that have
at
least one reference per sentence. So concluding that any single unreferenced statement no matter how many other referenced statements
there
are in the item brings an entire Wikidata item into the "untrustworthy zone" is just silly.

Hoi, Maybe.. but not all Wikipedias are the same. It is verifiable that Wikipedia would easily benefit from Wikidata from Wikidata by replacing
the
existing links and red links with functionality that uses Wikidata.
It happens often that I work on content in Wikipedia and find an error
rate
of 20%. When you check Wikidata for its quality I expect it to be much better than 90%.
It is blooming obvious that Wikipedians only see fault elsewhere and
are
forgiving for the error in their own way. Thanks, GerardM

What you hear is "Wikidata is unreliable" (compared to the

Any non-trivial content you want to add to Wikipedia today has to
fulfil
one basic criterion: that the content be traceable to a
professionally
published source.
Most Wikidata content fails that criterion.[1] It's blooming obvious
that
Wikidata is "unreliable" according to Wikipedia's definition of a
"reliable
source", isn't it?[2]
