You see, you think it is noble and right to want to get married, probably to have children. But this is how it is...
The children, whether they are biologically yours or not, they are never truly 'yours'. Children belong to the state, or the society they will live in. You are mostly having and raising children for the government/society because there is no doubt that will influence them more than you. Also, after a few generations your own genetic and cultural influence on you children will mean nothing after they have married and had children themselves, after a 100s of years your impact really will amount to very little.
The nuclear family system is never about the man, it is always about the system, religion, state that it is happens within, the nuclear family is simply there to propogate that system.
Now, if you join a cult, a commune, a different religion, and then promote that system, and help to grow that system, then you are actually more likely to leave something behind that can propogate and continue.
What I'm saying is, if any mans really wants to leave a legacy, affect the world etc it is not about having a nuclear family but really changing the system, affecting politics, being part of a community etc cos those things can grow over generations and actually affect how future generations behave.
I mean its cool to get married, Im not saying dont do it, Im just saying its not really the best way to have meaning in your life, to have a legacy, or to be good and noble. At the end of the day, whats the point having children if you cant even give them anything other than to place them at the mercy of this system and these values. In that case it maybe better to try and change the system for the benefit of future children whether yours or those of others.
