What in the world do you mean by a "continuum category"?
Cells in your body divide and produce other cells.
Each cell will have a continuum of division that would actually be traced back as far as life existed.
So there are various categories of division of these cells as these follow different strategies. There are ones that divide and replace cells in your own body to keep you alive. There are some that divide and expect external genetic material from to begin a different continuum that results in a huma being, which is the second continuum.
So, there's a division that keeps your body alive, and there's one that keeps all of us alive as humanity over extended period of time.
Your individual continuum is merely a chunk of our collective continuum.
I think it goes withiut saying. The eggs that are dying off are not the same as the ones that fertilize and don't die off. You are attempting to put these in the same category and these clearly not in the same category.
So, it's not a single life that you are terminating on that continuum once that process passes the threshold if a different continuum. You may be eliminating hundreds, or even thousands when it comes to the continuum of human lives that could result.
You are alive and experiencing life precisely because of that unterminated chain of continuum as a process of human species as a collective.
Hence that's why we actually have collective morality as it pertains to individuals. We can't survive as individuals. We are not hermaphroditic. We only survive as a collective.
When you begin talking about it using reductionist analogies, you are attempting to hide who you are and your individual responsibilities to humanity in general.
The reason why you want to have sex is because sex is a mechanism for something very specific. There are zero reasons for that mechanism to exist otherwise.
You can redefine the meaning of that mechanism, but in such you are redefining who you are without any justifications to do so.
The reason why you exist today is because there are billions of cells that "sacrifice" themselves as these maintain the continuum of "you" ... And because there are millions of other people who did the same. The reason why we have all of the sacrificial motiffs in religious narratives is precisely because these reflect our internal mechanisms.
Abortion is a denial of who you are when it comes to a reason for you existing as a mechanism in reality.
And when you begin doing that, then your existence is detatched from any meaning and is rather arbitrary. We can't discuss any rights apart from what you are as a human being and what our individual and collective responsibilities. For every right there are numerous responsibilities. You can't detatched rights from responsibilities.
