You make some good points, but I think I prefer all of those problems to dying before I've even lived for my first century. :-)
> If we are given the capability to remain sexually active for hundreds of years, then one person will be capable of multiplying into far more new people, rapidly increasing population growth.
People can be sexually active without being able to have children. Ask anybody who's infertile, or uses contraception.
> Any disease we are unable to cure with the potential to permanently affect people will instantly become far more terrifying. Non-fatal sexually transmitted diseases, loss of limbs or appendages, and debilitating mental diseases will be far, far more damaging given the greater lifespan that they will affect.
That is as it should be. Horrible things are horrible; that they are overshadowed by worse things does not make them any nicer.
> Medical care will still, presumably, be as expensive and challenging as ever; however, we will have more people who need it and more reasons that those people need it.
While it's possible that medical care will continue to cost the same amount for the next few hundred years, it seems kind of unlikely. A lot can happen in a century.
