The Money mechanic is a double edged sword, if red at any point causes a failround, blu will be low on money funds. Which just allows reds to cause failrounds on end, whether that be with sentry car or body armour. A scout is required on blu just to prevent reds from leaving out the back secret, especially when there aren't the funds to fortify the breakables. And with the current state of blu players (myself included). it's difficult to prevent failrounds once reds have the money to buy overpowered bullshit every round. Although I'm pretty shit at the game despite having 1300 hours.
