I haven't seen anyone talk about how easy it could have been to supply the city given the intent but I agree with you that it's a silly statement. People don't understand how desperate it was. There was enough food in the USSR to keep it supplied, but creating a logistics chain from literal scratch in the middle of a war when not even the army has enough trucks and other logistical supplies for its own needs is a dire situation. The trucks from lend lease were a massive help.
