Maybe part of him, and while I think Ralph is a political chameleon in many ways - I think he at the very least enjoys the trad aesthetic.I think a very idealistic, optimistic part of Ralph thought having a kid would force him to get his act together. Now it’s just another mess he’s made that so pains him to ponder that he needs to be wasted during his waking hours. Imagine trying to run from yourself 24/7, knowing you’ll never escape. What a way to live.
Much like a child who wants to be a vet when they're older ignores the downsides of the job, like throwing dead kittens in the bin, fisting horses anuses and cutting off dog testicles, Ralph like all these trad larpers want to feel trad and superior without all those pesky responsibilities, and without all those horrendous social pressures that have driven people into dark places for not measuring up.
TL;DR Ralph, like a child, cannot see the consequences of his actions.
