When talking about a maximum life extension therapy it is intuitively credible that the moral judgement concerning this treatment will also depend on the putative cost of the technology. To handle this situation clearly, it is worth differentiating between three different conditions.
First, when the expense of the treatment (let it be the cost of one complete regeneration of an adult human body, i.e. the regeneration of all body parts, organs and tissues) is so high that only the richest people can afford it and the state obviously cannot guarantee it.
Second, the treatment is quite expensive, yet it is accessible to the large part of the middle class, but the state again cannot guarantee it.
Third, the cost of the treatment is cheap enough that the state can guarantee it for its citizens.
Life extension as business will also depend largely on the cost of the technology.
