Because none of the players involved in the Euro finals are available
12 players out of the original 33 were unavailable due to playing in European finals. Greenwood was sent home due to injury, Sancho was unwell and Henderson not yet fit.
So that's 18 players available to play and you think Southgate is going to tell those 6 players who didn't make it to jog on? Leaving 12 players to face Austria and risk more injuries and fatigue to key players. He'd be slaughtered completely if he did that, can't win either way it seems.
