Gr3y so using your code of ethics it's ok to exploit people if they agree to it.
I'll go and hang around outside a food bank or Jobcentre, get myself a cleaner for £2 an hour from someone desperate enough. Buy someone's bone marrow from a supported living centre. Maybe hang around in a deprived area and get a kidney. I found the toddler stage more fun, so perhaps I can find someone with pnd I can convince to sell me their 2yr old.
Oh no, silly me, they're all exploitation and we have laws to prevent me using my privilege to take advantage of people that may be vulnerable. Unlike the noble cause of buying a newborn.
Unless you think the law should be changed so I can legally do all the above, and you'd be quite happy for me to exploit your dc/dp/ parents/ siblings then it's hypocritical to agree it's ok to buy a newborn.
Bollocks to it being about the genetic parents.
Do you think someone that gives birth to a baby as a result of embryo transfer would hand them over cheerfully in the event a mistake had been made and it wasn't their biological child?
'Expenses' are a joke too. If surrogates were people like me they wouldn't really have any. Enhanced maternity package would cover loss of earnings, so a three figure sum at most for maternity clothes and travel costs. Except that's not how it works, because financially comfortable women aren't surrogates for strangers.
