I am a person with several hobbies, with photography being one. I bought a 5DIII and 24-70 f2.8 on impulse for Christmas. I sold my 7D and 50 f1.4 to help recover some of the cost. I love the 5DIII and 24-70 combo. I also want a 70-200 f2.8, but the Canon is just too expensive for me to justify, even though I can afford to buy one. The Tamron 70-200 f2.8 VC on the other hand is in my sights. I've rented both, love the Canon, but the Tamron is good enough for my needs.
For the professional, I can see spending "L" money. For a person like me that just shoots for fun and enjoyment, maybe not.
