Why do socialists hate the market yet use it for their needs?

Socialists have to eat, wear clothes, stay warm in the winter, use transportation, etc., like everyone else. They could live in public housing, use public transit, and get health care supplied by the state. But for their other goods and services, they have to go to the market for the things they need or want. How can they reconcile their ideology with their actual behavior? Are they hypocrites?
