Pregnancy with no limitations and childbirth with no pain

In this article -  The psychological trauma behind surrogate pregnancies
- the author makes bold statements regarding the motives of the parents who decide to outsource pregnancy. He suggests they do so in order to avoid the discomfort and physical limitations of  pregnancy and the pain of childbirth.
I suppose many parents for whom hiring a surrogate mother is the only way to have a genetically related baby would disagree.

But let's imagine it's all true and money is the only issue.
Some choldfree don't want kids and it won't matter for them that a painless option exists. Some are afraid of  pregnancy, birth and sleepless nights. If a couple can pay for a surrogate, obviously they can pay for a nanny.  Just curious how many childfree couples may change their view on childbirth if surrogate pregnancy becomes more of a mainstream.
