You seem to have a very wierd concept of "Consumer Rights"
Consumers have one right and one right only: The right to purchase or not purchase what they want. It's also the most powerful right. The only way this right gets stepped on is no-returns policies, which negate the right to "unpurchase" a product.
Also, all computer software has bugs, some more notable than others. Despite what you may think or see in a game, every line of code depends on every other line of code. Expecting Skyrim to be less buggy than Microsoft Office is a sign of serious delusion or ignorance.
Furthermore, every month of bugfixing is a month that could be spent on creating more content for the game. It can take weeks to figure out why chickens are in league with the City Guard, or dragons are wearing Party Hats that they don't have, time often much better spent on making it an actual, playable game. "Sorry there's only one weapon in the game, three skills, and movement is restricted to the Cardinal Directions, but by the time we were done bugfixing, we didn't have time to add anything else"
IMO, it's better to have a game that doesn't always work as intended, than to not have it at all.
