Yes, blue origin was founded in 2000 and spacex founded in 2002.

Blue origin landed it's first rocket in 2005. It was a tiny rocket and a tiny flight and purely for testing.

SpaceX landed it's first rocket in 2015. It was an orbital flight delivering real value.

Would it have made sense for SpaceX to stop because blue origin already flew a reusable rocket?

If you're counting Blue Origin's Charon test vehicle, SpaceX had Grasshopper going several years before 2015, and they'd achieved orbit in 2008 already.

Sure if you pull the date of the first landing I'll update my comment.
