I didn't get selected because... I have a happening life?

So I interviewed for a SaaS company serving US clients. I got selected after three rounds (basic email chat, built a project, technical coding round at last) and got selected. Finally, it was time to discuss salary and joining date with the CEO. He was impressed by the about section on my portfolio, where I mentioned that I like to go on treks, hikes, read books, lift weights, go on a run, etc. During our call he mentioned that everyone at the startup works 6-7days a week, 12hrs a day and asked if I'd be fine with it as I have a "happening life". I said that I'm not used to it but I'll manage and work in appropriate working hours. He seemed to agree on it. But he ghosted me after that, and when I pinged him in the email thread; he said he's not moving ahead with me because my other properties won't allow me to "work as much as other employees". How am I supposed to react to this lol
