Tor exists, but realistically the overhead of using Tor is not acceptable to the general public. As long as Tor is sufficiently slow compared to everyday traffic it will remain a niche use case. A good VPN on the other hand gives you at least a little bit of privacy without much of a cost.
I've looked at Tor recently just out of curiosity for the tech and I found browsing to be plenty fast. Admittedly it was plain text sites with no images or whatever. And the installation/use of the Tor browser was easy.
