How so? Currencies are only an abstraction layer on top of goods and services. Instead of directly trading my goods and services for yours, we use a currency--a common "interface" for doing so. The currency doesn't have intrinsic value; the reason it has value at all is because you can exchange it for a wide variety of goods and services. That's why people want dollars, but not Monopoly money.
It isn't though - it's a way to illustrate Bitcoin's usefulness as a currency as "worse than gold."
I'd put bitcoin's inherently deflationary nature, inability to perform chargebacks, vulnerability to selfish mining, incentivizing the waste of electricity, or a myriad of its other problems far higher on the list than the fact that it has no intrinsic value. Outside the above argument, its lack of intrinsic value isn't that common a criticism, nor is it really relevant.
