I notice that we tend to overestimate peoples' financial situations. Everybody agrees that the price Tsuji wanted to ask was way too high, but to then point towards the ~$50k price tag of Stemson as "being available to the common man" is way too optimistic. Most people live paycheck to paycheck and would be willing and able to pay such amounts only for necessities, such as a car or house, or investments. This treatment is neither.
Most of the people who could afford it, will likely only be able to pay for the procedure once. So if results aren't guaranteed for a lifetime, that should make you rethink the decision to undergo this procedure.
