Many people hypothesize similar things, but there is as yet no real reason behind these hypotheses.
Still, it would be an extremely exciting discovery for physics if it turned out that a QC is not physically realizable. It would prove that quantum mechanics is not the final description of the world, and it would likely be a huge step forward for understanding the measurement problem.
