From watching pros play, an early wall-off can be vital. At their level of play, slipping in 1 to 3 combat units can have devastating early effect. Terrans can easily solve this by including a supply depot in their wall, which can be raised or lowered at the push of a button. Or a building that can lift off and reposition.
Another take: Especially in a Terran vs Zerg game, the Zerg's creep kind of acts like an inverse blockade. Since Zerg units move faster on it, and the Zerg player will have vision of what's on the Creep, the Terran will often prefer to slow-crawl their siege tanks and etc closer, and be forced to use resources to clear out the Creep before moving too far in. Stronger Terran players can often be proactive about pushing back Creep, and have an easier time applying pressure.
For those who don't know, Creep is a purple-ish goop that covers the map terrain (requires active effort to propagate), and Zerg are bug-looking alien things that grow out of eggs. Terrans are the humans.
