It's the other way around, while initially it will only be available to elites and prisoners (if you are innocently convicted for life, the digitized brain can set the record straight and provide another life, some will take that option, others wont).

As the technology improves, it will be mostly just for the rich and less for prisoners, and as costs fall further there will even be financial pressure for the rest of the population to "go digital": insurance on digitized lifeforms will be much cheaper, replacement robot body parts, replacement electronics, versus expensive healthcare.

Look up the fraction of GDP in developed nations that goes to healthcare and insurance. People will be shamed by the economy as if they are uppity for hanging on to their slow, expensive to feed and maintain meatbag bodies.
