Which maybe another reason it decided to have Barry occupy it, so he could not only serve time for his mistakes, but also work on undoing the prison, redeeming himself since his actions were how the prison was created in the first place. I may also require the help of more than one speedster, which could lead to the SF letting him leave for a bit to get the energy needed for the task. Once done, the SF will reward Barry for redeeming himself by not only letting him return to earth more powerful and wiser than ever, but to commemorate it and to be sure hat he never forgets his lesson, the energy for the SF Prison will be used to make a new suit for Barry that draws closer to resembling the Future Flash's suit, but not quite yet as a sign that Barry still has growing to do.

Get it? He is not in prison because Speed Force said Barry is going to a paradise. The timeline could been reset and a new Barry will take place. Still he could figure out a way to undo the prison to redeem himself.
