That's a completely bullsh*t analogy and you know it.
Anyone who claims bullsh*t invariably hasn't checked up on their 'facts'.
Largest ones now installed can supply 3MW and designs for 10MW versions are in progress. These are estimated to produce minimum 30% of their maximum output spread over any year.
The land area you are talking about was a complete fabrication, Modern turbines are much bigger than the tiny ones that were available when that myth started. As you rack up the size the area needed drops drastically meaning you only need thousands. Most will be put up out to sea, not affecting land at all.
