Or is it that you do not understand ERDs? Hmmm...It is sufficient for a counter example to disprove and assertion, but an example is not sufficient to prove an assertion. So I leave you the easier task.

Can you substantiate your statement? Provide an object model that is not equivalent to an ERD with an extention of adding methods as a counter example and your statement will have more merit than mere opinion.
