...They made it so that you can catch the legendaries to sell the games. That's all.

If they didn't, everyone would be complaining that you can't catch them when pokemon's slogan is literally 'Gotta catch 'em all', and the games wouldn't sell as well. It was a marketing ploy, nothing more.

That being said, if the pokemon world was real, there's no way in hell you would be able to catch legendaries or semi-legendaries (I'm looking at you guys, Suincune, Raikou and Entei) simply because they are supposed to be so powerful. I mean, Entei has the power to make volcanic erruptions when he roars - in real life, he'd just make one under your feet and be on his merry way, and he's not even an actual legendary.

But sadly game sales win out over logic, and so all pokemon in the games are catchable.
