I can't walk into a store and pay with USD either. It doesn't mean USD is not a currency, it's just not usually accepted by stores in my country.
I use Monero semi-regularly to pay for things online (usually privacy products, because sadly nobody is interested in selling me groceries in exchange for xmr). You can absolutely buy things with it.
