> Web developers are a dime a dozen, so I doubt if companies would really want to pay for a remote worker when they could easily get a handful just round the corner.

What exactly do you consider a web developer? If you're talking about the kind of web developer who codes a web page for his grandma's flower shop in html & css then I think you'd be right about that.

But if you're talking about one who writes backend code to scale, parse data and interact with external services or writes frontend code using whatever the latest javascript framework is these days, then those web developers definitely aren't "a dime a dozen". And they certainly won't have problems getting a remote job.
