Nash said he can totally afford child support ... he just doesn't want it to ruin his kids: “I don’t want my high-privileged lifestyle ... to be an artificial environment.”

Of course, Alejandra doesn't believe that -- she thinks Steve's trying to block her from moving the kids to L.A. because the Arizona courts aren't making him pay a penny in child support and he's afraid a California judge would nai
