The good thing about QR codes is there's lots of capacity. Hashtags would become more complex and longer as additional locations are included, whereas QR codes look the same.

I understand the capacity point, but for geocoding a geohash would suffice. Place the geohash under the name so mobile apps can read it or people can type it in (easier than a qrcode)

    Eiffel Tower
    #QWERTY986543

Even wikipedia could sell vanity tags to the city council like:

    Eiffel Tower
    #W/EIFFELTOWER

Or something like that
