There is only one problem with that. Which is, that it may not work out in the long run.
Say you get married to a guy with a really good paying job. You can afford to stay home with the kids and not work. You miht be content for 5 years, or maybe 10 years. Maybe 15 or 20 years. Then what if your marriage isn't working anymore, what if you find out your husband is cheating on you? You will not be able to leave him and continue life on your own. You will not be able to get a job after sitting at home for a decade. You would be dependent on your husband so you would have to tolerate him cheating on you and he would never stop doing it because he'd know you will always believe he never do it again, and even if you don't, you can't leave him so he can do whatever he wants.
Maybe he won't even cheat on you, maybe he'll just leave you for someone else one day and then you will be out on your own, lost, with no money like some kid who got disowned by their parents.
Or maybe there will come a day when you don't want to be married anymore. What if you want to divorce him because you don't love him anymore or whatever reason but can't because you cannot financially support yourself?
This scenario happens ALL THE TIME. Most marriages end in divorce and handing your life over to someone is not a good idea. Women who have done nothing in their lives but sit at home are no different from children. They wouldn't survive out in the real world on their own. They're like heiresses who live off daddy's millions and live like children all their lives. You can get off your lazy ass and do something with your life, as everyone has to, or you can marry a guy and pop out some babies and be his slave for the rest of your life. Do not complain when your laziness backfires on you.
