The terms "block level" in an HTML context and "block level" in a CSS
context are unrelated. It is quite possible, legal, and often useful, to
write things such as:

   p { display: table-cell; }
   span { display: block; }
   tr { display: inline; }

This does not in any way affect the meaning of the elements, nor their
allowed positions in the HTML markup, it merely changes what they look
like.

By default, everything is 'display: inline'. Thus, the rule

   p { display: block; }

...is actually needed somewhere to get the usual effect that is expected.
User agents put this rule in the user agent stylesheet, so authors do not
have to put it in theirs.
