The speaker's opinion is that birthcontrol is selfish, not that people shouldn't be permitted choice in the matter.
And the opinion is nonesense, because it depends on individual circumstances. Sometimes it is, and sometimes it isn't. Some couples are not fit to rear children for a host of reasons, including not wanting children, and some are not fit to raise more than a certain number of children, due to emotional and economic reasons, and few I think are fit to raise more than 3 or 4, unless they give that task their total and absolute emotional and financial attention, and are totally committed to it.
