What I'm saying is that the rules are ALREADY like that.
Not really. I'll explain below.

Level 2 = CR 2 = Ogre = ECL 2
Not exactly. One common oversight that some people suffer from is this: Your CR is a measure of your power, and your power is also affected by your resources. A standard core race PC at any particular level has a certain amount of resources available to it. These resources, measured in gold pieces, are what allow you to get weapons, magic items, spells, potions, tools, armor, etc. All of this gives you power, and that power is limited my your resources, and your resources are limited by your level.
A monster also has a certain amount of resources available to it, such as attacks, hit points, special attacks, special abilities, special qualities, spell-like abilities, supernatural abilities, extraordinary abilities, damage reduction, energy resistance, energy immunity, etc, etc. These resources are limited by the monster's CR.
Now, if you take a monster, which has a set amount of resources based upon it's CR, and make it a player character, you are effectively granting it even more resources to allow it to aquire weapons, magic items, spells, potions, tools, armor, etc. Thus, it's effective character level is increased due to the fact that it already has it's own resources.
So, presumably, an Ogre is ECL +5 because it starts with the resources equal to that of the average 5th level character. Now, where ECL breaks down is when you actually compare the monster to a PC of equal level. For instance, compare a young bronze dragon, which has an ECL of +17, to that of a 17th level character of any given class. Are they perfectly equal? Nope. They all have their different advantages and disadvantages, such as melee capabilities, ranged capabilities, magic capabilities, etc, etc.
However, the primary flaw of ECL is the fact that monsters were designed to exhist for but a few rounds, or minutes, at the most. Thus, their resources (such as attacks, hit points, special attacks, special abilities, special qualities, spell-like abilities, supernatural abilities, extraordinary abilities, damage reduction, energy resistance, energy immunity, etc) were geared for a specific purpose, such as melee combat, ranged combat, magical combat, swallowing opponents, grappling, etc, etc.
The core classes were designed, in theory, to be balanced with one another. Even though on class is more focused on a particular area than another class, they are balanced with one another. ECL is used to balance a monster PC with standard PCs, and with the game as a whole. ECL is used to balance a monster, as if it were a class in and off itself, with the other classes.
At least, that's the way it's supposed to work. But like I said, ECL isn't perfect, but neither does
level = CR = monster = ECL.
