It is a serious issue. It is not comparable to your examples.
It's a very good kashya. Why did the Torah give a man the power to screw over a woman for life?
I've yet to hear a good answer.
And I just add it to the hundreds of kashyas that we don't have a good answer for.
There are those that because of this problem change the Torah. That's a big problem.
We're not smarter than Hashem.
It is not at all clear that the drasha of vekasav lah and rules related to it are divine or from "the Torah" and may have been layered on by the power granted to the chachamim to be doresh (still with power of chamirus of "de'oraisah", but considered Divrei sofrim, and subject to change by later Batei dinim, all per the Rambam's view on Sinai vs Rabbinic law, and the fact that any drasha on which there is machlokes cannot be from Sinai per se (see Gittin 26a as to the conflicting opinions on the extent of lishma requirements per two reads of R Elazar)).
All the torah says (and indeed a simple read could be,and perhaps the mesorah read of the simple text ) is that if u hate your wife, u have a mitzvah to write out a bill of divorce stating the separation details (u get back this, i give u this etc.), and send her away. So no blame on Hashem, or any right the "Torah" is giving to men, though i also think the rabbanan that enacted, accepted and enforced all these rules through drasha etc did it for a positive purpose (to keep marriages intact and protect poor divorcees who would have nowhere to turn in those days, similar to all the leniencies made with respect to the protection of (real) agunos who lost their husband in questionable circumstances and wanted to remarry).
I'm sure peeps here will say oh this sounds like reform/open orthodoxy, but this is all pretty well settled based on the Rambam's view of Torah Misinai, the two types of drashos (those that are done to placehold for something we also got at sinai vs innovative rabbinic drashos) and machlokes. Read the Rambam's intro to pirush hamishnayos, and also check out Hilchos mamrim in the yad.
