I think you're missing the fact that our entire world is being slowed down by this system, and a few tweaks are not going to change that. Yes it is true that in the current system Google could ask for permission to license this one patent, but what about the broader implications of patents as I have laid out? What about the people all over the world living in worse conditions than necessary due to intellectual property restrictions? How many people could have been enjoying a worldwide free library if Project Gutenburg had been allowed to continue? How much cheaper would cars and auto repair be if manufacturers cloned and copied each other to settle on a set of standard designs, as has been done in 3D printers? How many lives would have been saved in Swaziland/Eswatini in the 1990's if the WTO had not outlawed low cost clones of effective AIDS medications? [1]

For every potential startup founder who will only work on their problem if they can get paid, there are IMO 100 people who will work on a problem because they care about solving it. I don't think we would lose much if those motivated only by profit had less incentive. And keep in mind they would still have first mover advantage. Plus huge companies often don't care about little corners of the market, and there is lots of room for companies to serve market needs the bigger companies are ignoring. But if another company wants to compete and they can actually do a better job? We are hurting society if we restrict their ability to do that.
