For bare trademark searches, we could write laws that allow competitors, but restrict taxing and bidding off the reserved mark above the trademark owner's result.
You should be able to explicitly bid on trademarks because you intend to compete directly with that business. Nobody should ever have a legal right to appear at the top of search rankings for anything. Laws restricting business competition are almost never a good thing.
