It's analogous to testing itself. Testing cannot prove the absence of bugs, though it can find them. Similarly a coverage check cannot show that your test suite is adequate, but it can show it to be inadequate (or perhaps reveal dead code to prune).
Nobody is claiming that coverage is the be all and end all of testing. That does not mean it is useless to measure it.
