The embryos that you speak of are months old. The embryos used for actual research are only days old and don't even have chances of becoming fetuses. At this stage, they are just blastocysts; a cell that is just a cluster of different cells. They can't think past breathing. The fact is that they are not humans yet. They have no organs, limbs, eyes, a nose, a mouth, and most importantly, they have no conscience. They have no families.

Fully developed humans take precedence over cells. These people actually had lives and have families. One of the diseases that stem cell research can possibly cure is parkinsons. People can go from blabbering, twitching shells of themselves, to speaking and walking humans. Using your argument of comparing a cell to an actual human, you can't compare 5 years to a few days. 5 years to this human's life is 5 years with their grandson. 5 years to this human's life is 5 years with their husband. 5 years to this human is 5 more years to live. 5 days to an embryo is 5 days until its death.
