You are completely missing the point. Fatherhood is important and I haven't said anything remotely to indicate that it isn't. The problem is, masculinity as it is constructed in this culture is terrible - for women, but also for men. It harms everyone and makes women not want to partner with guys who are steeped in archaic ideas about what relationships ought to look like. Men are capable of changing this - they mostly just don't want to.

The goal is not to make men irrelevant, but it is going to be the outcome if more of them don't come around to less entitled, less harmful ways of expressing masculinity.

Plenty of people have wonderful, meaningful lives without marriage or children, but it's also fine to want those things. However, imagining that they will automatically imbue your life with joy is once again nothing but a fairytale you seem to have bought into. Good relationships are a lot of work, and parenting is nothing but constant work, with little reward for a long, long time. It's great to want to build a family - but for the right reasons - not to fulfill on some sort of narrative you have in your head. Honestly, it's like I'm talking to a little girl who has watched too many princess movies. Getting married is the start of a whole lot of work - it's not some magic Utopia where now everything is wonderful.

Relationships take a lot of cooperation and communication, as well as continued work on your own stuff so you don't try to work that out on your partner. Turn your attention to understanding who you are, healing your baggage, and being great at the skills that make for strong relationships - for your own sake - and the chances you will meet a great partner go up exponentially.
