The people making the legal arguments for same-sex marriage did not base their argument on any anticipated "land rush" of same-sex marriage. The The legal arguments merely asserted that the prohibition of marriage to same-sex couples was unconstitutional. 

This article's entire premise is ridiculous on its face. The rate of same-sex marriages bears no relationship to its legality. Would Austin Ruse, this article's author, snear at the Loving v. Virginia ruling that ruled all laws against mixed-race marriages to be unconstitutional? After all, following the Supreme Court decision in the Loving case, the rate of mixed-race marriages was only 3 percent of newlyweds. By 2015, 17 percent of marriages are mixed-race marriages. That's a steady 5 fold increase in 50 years. But it's only been 2 years since Obergefell. Let's wait 50 years for today's homophobic bigotry and social stigma to decline and see where we are. Who knows... maybe the Washington Examiner will still be here to report it.
