There are a lot of legitimate use cases that require reliable location data. I mentioned a few that I could think of in a sibling comment, but I'm sure there are more. Maybe you can come up with a use case for accurate location data yourself?
Anyway, spammers and data brokers probably wouldn't care at all if say 10% of people spoofed their location. They don't really have a lot to lose if some of their data is incorrect.
Users also need other users to be honest about their location. Consider a dating app; you want to meet real people who live in your area, not a fraudster pretending to live just a few blocks away.
Or a delivery driver: You want them to actually drive up to your house and ring your bell, rather than just pretend to drive there and drop your package somewhere else.
Location data is worth a lot more if it is reliable.
The user should be in control of sharing their location. But you shouldn't be able to just provide a fake location.

So you shouldn't be able to use the dating app to set up a date for when you're back home while on a business trip or holiday?
Maybe you should just upload proof of residence to the dating app instead. But I'm sure you'd consider THAT a violation of privacy, while 24/7 location tracking of your phone isn't because ... it's electronic?
By the way, do you want to give your exact location to a profile on a dating app? Even if they're local, maybe they're serial killers.

This other case is legitimate but it can be solved by issuing the driver a work device that has tracking.
Unfortunately the other 10000 cases are unneeded violations of privacy.
