Because that introduces certain kinks into the game mechanics that could prove troublesome.
You're speaking here in terms of PnP, right? There have been systems for bending metal bars in all the D&D core books, just in case.

If a thief is wearing gloves of ogre power +4, what's to stop him from using his magically enhanced strength to beat down doors, bend iron bars, punch through stone, etc?
In 3.5 Ed. D&D, investing a lot in STR is not very helpful for Rogues on the long run, especially if they adventure with a mixed group of other classes. STR is not extremely helpful to them for melee combat purposes; their greatest source of melee damage comes from Sneak Attack, which adds extra dice to damage unmodified by STR, and they can apply DEX (their primary Ability) instead of STR to their melee attack rolls thanks to the Weapon Finesse feat.
Breaking doors and bending iron bars with your bare hands requires a bit of STR, but it's not an extremely spectacular feat. Breaking down a strong door and bursting through ropes requires a STR check DC 23, while bending iron bars is DC 24; a character with a STR of 18 can bypass those obstacles simply by Taking 20. Punching through stone is a bit more difficult; a wall with just one inch of thickness has a hardness of 8 and 15 HP, so you'd need a STR of at least 22 (+6) to be able to deal even 1 HP worth of damage with your bare fist, with a lucky roll, assuming you're a medium-sized humanoid with no special bonuses to unarmed damage (1d3+6 = max damage of 9). This would be a messy procedure that takes dozens of rounds to finish, makes a lot of noise, and shakes the whole building. STILL, your average rogue with a base STR of, say, 13, would need more than those Gauntlets of Ogre Power +4 to be able to even bend iron bars. And that rogue would rather be wearing some gloves that boost DEX.

If a warrior has 26 strength, according to 3.5e that means he posesses superhuman strength (10 is the average human's strength, 20 being Conan, and 26 being Superman), why doesn't he break his weapons accidentally every now and then when he grips too hard, or why even bother using a piece of steel to attack with if his fists can punch through stone or bend iron like a pretzel?
A character with a STR of 26 can barely lift a clown car off the ground. That character may carry up to 920 lbs. above the head, lift up to 1840 lbs. off the ground, and push around up 4600 lbs. Small cars like the Prius weigh in over 2000 lbs. Superman? More like... SuperGimp! LOLLERCAUST!!!
There are no rules for "accidental weapon destruction by death grip", you'd have to attempt to break it willingly. Weapons offer the benefits of extra damage, extra reach, wider threat ranges, and special bonuses to trip and disarm if you don't have levels as a Monk or some other unarmed-specialized class, plus you don't provoke an Attack of Opportunity if you don't have the Improved Unarmed Strike feat. Plus it doesn't sting as much when you're trying to smash your way through a rusty, spiky door, or a creature from the plane of fire, or an ooze.
