From your list 2, 3, and 4 and I'll add he wants children to get back in with his father and mother thinking it will ensure he gets the inheritance. He salivates at the thought of getting King Roy's house, land and money. With a pregnant Gen Z wife, well King Roy can only be overjoyed at Lucas making him a grandfather, he'll put out the welcome mat and Lucas/wife will move right in. From there it's just a matter of King Roy providing for them and waiting for old Roy to kick the bucket. Of course Lucas thinks King Roy is not going to leave his grandchild/children in the street so he'll be leaving everything to Lucas.

How pathetic do you have to be, that one of the main reasons you want to bring a child into the world is because you want to move back in with your parents (the other reason is because you presumably want to groom and later rape the child after your ‘wife’ becomes an older crone at the age of 30).
I have a much better relationship with my family than he does (meaning we actually speak and enjoy each other’s company), but I sure as shit don’t want to live under the same roof with them ever again.
Secondly, when we do visit, you can tell that my kids wear my folks out. That’s not to say that they don’t love their grandchildren... they do. They’re just old and don’t have the energy to keep up with young kids day after day.
I don’t know much about the esteemed King Roy and his Kingdom of Elk, but I’m pretty sure welcoming in his obese, unhygienic, socially repulsive, mentally unstable and likely violent man child of a son, the woman who decided to bear his child (if such a woman existed she’d come with a whole host of issues) and a newborn doesn’t sound like how he wants to spend his retirement.
This is probably my least favorite part of the sheer repulsiveness that is Lucas’s personality. I waited a little while to have kids. I knew I wasn’t responsible enough to have them before I did and I wasn’t in a financial place to support them. I know it’s not in the cards, but this mentality he has where he’s going to knock some girl up and then magically figure out how to manage his life afterwards just strikes me as pretty gross. Couple that with the fact that he’d be an atrocious father, a terrible role model and that there’s a more than 50% chance he’ll end up raping that child and I just get more than a little disgusted with him than usual.
Here’s the thing though, when King Roy and Myrna pass on through into the great beyond, whatever material possessions they have left will be distributed, not to Lucas but to his siblings who actually spend time with his parents, don’t eagerly wish for their demise and actually are going somewhere with their lives.
Like the Gen Z beauty queen who can’t wait to become a mother and has a fetish for obese smelly hobos, an inheritance just isn’t in the cards for him.
