You see that women will be allowed to just donate their eggs as long as it is allowed under federal law.
The argument was that women could "sell" their eggs just recover "unpaid wages" if they were unamployed or something. It's a process that does require some down time, so they could possibly get by with it.
In that case, the women would wind up with a minimum benefit, while the actual people who harvest them make tons of money.

(4) No person may, for valuable consideration, purchase or sell human blastocysts or eggs for stem cell research or stem cell therapies and cures.

(17) “Valuable consideration” means financial gain or advantage, but does not include reimbursement for reasonable costs incurred in connection with the removal, processing, disposal, preservation, quality control, storage, transfer, or donation of human eggs, sperm, or blastocysts, including lost wages of the donor. Valuable consideration also does not include the consideration paid to a donor of human eggs or sperm by a fertilization clinic or sperm bank, as well as any other consideration expressly allowed by federal law.

Under those circumstances, it is a fair point.
I can see both sides.
