The use case for TOR is illegal activity. Some illegal activity is not immoral, like organising a protest against a dictatorship. But Tor is not a useful tool for simply browsing websites. The inconvenience isn’t worth it when a regular browser fulfills your needs better.
It’s like money laundering. It could be done recreationally, but that’s not the normal use case.
Those layers get in the way of casual browsing. Like you could use a bucket to fill a full size swimming pool, but a hose is better suitrd for the job.
It's more than just privacy. It allows you to visit .onion sites, which will not load in a traditional browser. As a harmless example, this is Duck Duck Go: https://duckduckgogg42xjoc72x3sjasowoarfbgcmvfimaftt6twagswzczad.onion/. Trying to click that in a normal browser doesn't work because they don't support the onion network. But using the Tor browser unlocks that as well as all sorts of nefarious sites that you can't access through a "normal browser"
