My Wife Ruined Everything at Our Daughter’s Party — Now Everyone’s Blaming Me

When I tell people this story, they either call me heartless or say they totally understand where I am coming from. I am honestly not sure why some think I am the bad guy here, which is why I am putting it out online. What would you have done in my place?
My wife and I always dreamt of having grandkids. My daughter is my only child. We worked hard all our lives. We saved, invested in property, and built something solid to pass on.
I always imagined grandchildren running around, knowing that everything we worked for would go to them one day. But now, that picture is gone.
My daughter is now 36, unmarried, and doesn’t plan on ever having babies. I strictly told her to reconsider or bid her inheritance goodbye. She laughed and left.
The idea of my life’s work just ending with me is hard to accept. For me, inheritance is about family legacy. It is about passing down something that keeps our name alive. If there are no kids, no grandkids, then what is the point?
I told my daughter I will leave everything to my nephew, who already has a family. At least with him, I know my legacy will continue.
When she heard this, she exploded. She called me controlling and said I was punishing her for living her life how she wants. She said inheritance should be about love, not conditions.
We had a huge argument. She accused me of valuing hypothetical grandkids more than her. She said I was throwing her away just because she does not want children. I told her it is not about punishing her, it is about making sure everything I worked for does not die with me.
Now she barely speaks to me. I froze when I found out later that she is telling everyone in our connection that I am heartless and “old school”. I think she is selfish, and well, it is MY money. I have the right to do whatever with it, just like her right to remain childfree.
I know many people today choose to be childfree. I get that times have changed. But is it really wrong to want my bloodline to continue? Is it wrong to tie my inheritance to that?
