It’s an interesting thought and not one without any merit. My question is, where do you draw the line as to what is and what isn’t considered human trafficking?
Is the exchanging of money the reason one believes it to be human trafficking? If human trafficking in relation to surrogacy is about money in exchange for a baby then does it make it ok if a woman does so for free? Is it seen as human trafficking regardless of money or consent as it’s about the baby being trafficked? If so, are both the receiver and surrogate guilty of human trafficking? Is sperm and egg donation also human trafficking whether it be with or without a surrogate?
It also comes down to rights. Does a women have the right to do whatever she wishes with her own body regardless of the consequences to the potential child? Does she have the right to consent to surrogacy or is it always seen as exploitation, especially if money is involved? Do you believe in gay and lesbian rights and if so does this discriminate against them as surrogacy and donation is mainly the only way they can have a biological child? Does their potential rights out way any rights the child may have? If an unborn baby has no or little rights can surrogacy then even be outlawed? Would it only be a crime once the baby is born and handed over? Should unborn babies then have rights? The problem with rights in general is that the more rights you believe a person should have, someone else is possibly going to suffer because of them.
I do support a reforming of surrogacy and donations if it does not get made illegal.
I am surprised though that you believe what you do yet see Black Lives Matter as not a part of this issue. You should look into what the movement stands for as a whole. They are very vocal surrounding support for gay rights and for many that involves the right to a biological child so they very well may see differently to you surrounding surrogacy and the value of life due to this.
On a related note, look into ‘rehoming’ regarding failed adoptions, it’s a breeding ground for human trafficking of children sadly.
