There are ways to mitigate the long term aspects of WH SEO, among them starting from an expired/aged domain, using Wordpress features and plugins that (carefully set up) can automate aspects of ongoing SEO. Just don't go overboard in a manner that the new links, likes, etc are coming in too fast to be perceived as unnatural by Google.
In theory, if one builds a keyword list based on 60 terms that have only 300 monthly searches each, odds are you'll rank and stay at the top of page 1 for most or all of them, making ongoing SEO unnecessary. If you prepare 60 articles (one per keyword), published the first 15, but left all the others queued in your WP to post 2 per month, that would have your site auto-publishing new content for about 2 years without further effort.
