All forms of surrogacy should be banned. We shouldn't play with nature.
Altruistic surrogacy should be allowed. But, commercial surrogacy is objectification of the mother's body and open to abuse, hence should be banned.
All forms of surrogacy should be allowed as long as the true need is demonstrated.
It is a free society where consenting adults should be allowed to provide and use surrogacy services irrespective of situation. Governments and other regulatory bodies should not mandate rules for when, who and how, as long as misuse is contained through right laws.
