People have (or should have) the right to manufacture whatever products they want, and other people should have the right to buy whatever products they want. The only restrictions should be to prevent fraud (product has to work as advertised) and protect consumer safety (product shouldn't blow up).

You already have the right to pay extra for an extended warranty, or go shopping around for a version of X product that is user-maintainable. You also have the right to pay less for a shorter warranty, or buy a compact, tightly-integrated, non-repairable product. The EU's "right of repair" is merely a ban on the second category of product.
