I have zero doubt that there are flawed systems in some jurisdictions. That's the nature of the real world, with its ugly edges.
However a cursory examination is that MERS wasn't title registration at all. It was a registration of mortgage holders, where mortgages would be "assigned" to MERS. And the dispute wasn't over the accuracy of the rows in that database (which would be trivial to legally dispute and correct), but a technicality of whether MERS could be the one to foreclose -- itself a whole legal process, only at the very end impacting the title -- versus the one who assigned the mortgage. The net effect is identical, and I'm not sure if the difference between ABC Credit foreclosing on a defaulted mortgage versus MERS foreclosing means "stealing" someone's home.
