A 7-1 defeat to Germany put an end to Brazil's hopes of lifting trophy for a sixth time in front of their own supporters, and Rebelo believes that preventing youngsters from joining European clubs early in their career could help the national team achieve more success.
"It will be a deep scar for our football. But the best attitude we should adopt is to analyse the root causes and long lasting causes of that disaster," Rebelo revealed to members of the media.
"Our legislation makes it easy to export players abroad. We have the power in the hands of the entrepreneurs, the Europeans. They are experts in football services.
"We export the raw material. It is easy to do because you package it and you send it. For football services you have to add management and infrastructure that we don't have."
Brazil's final game of the tournament will be Saturday's third-place playoff against the Netherlands.
