Norway, where I live, has enacted laws banning inaccessible websites (with the exception of websites made by individuals). https://medium.com/confrere/its-illegal-to-have-an-inaccessi...

The law has been well-received both by the public and by businesses, with very few actual fines being issued, but many bad pages have been soft-forced into improvement. So it's actually possible, but will probably be much harder in the US, in which business, government and taxpayers/customers seem less aligned.
