Opt-out donation systems already exist in a number of places in Europe, including Spain, Austria, and Wales. While they can be controversial, there’s at least some research suggesting that they improve donation rates in countries that adopt them.
For instance, a 2014 review by U.K. researchers examining 48 countries with opt-in or opt-out systems found that donor rates were significantly higher in countries using opt-out regimens. (Interestingly, living donor rates were actually higher in the opt-in systems, although overall transplants for sought-after organs like livers and kidneys were higher in the opt-out systems.)
The U.S. government (which has an opt-in system) estimates that a patient is added to the national transplant waiting list every ten minutes, and that 22 people die every day while waiting for a transplant.
