"Lobbying is a form of advocacy that legally attempts to influence policy decisions"
I think there's a problem with definitions here. How the general public, especially here in the U.S., tends to think of lobbying is essentially always in the form of monetary value or gifts. In an ideal world, this probably should be banned for fairness reasons. Smaller institutions would always have necessarily less influence and power over policy.
In theory any exchanges of monetary value or gifts should be well documented and must be disclosed. In actuality, it's much harder to document than meets the eye. There are so many ways around it that it's almost worth saying it doesn't exist (admittedly it seems especially egregious in the US but I'm no expert on how its done elsewhere).
But then, at the same time if we conclude that it's hard to document then it's hard to ban it. Its just a slippery slope all around. Institutions must be allowed to petition their government, but making sure that doesn't go too far and lend itself to corruption is difficult to enforce.
So that is likely where the author and the rest of us lead to the conclusion that the eventual result of lobbying as its implemented in essentially everywhere in the world is corruption.

This is prohibited, not in an ideal world, but in essentially every Western democracy except the United States. I appreciate the political difficulty of implimenting this (or indeed any useful structural) change in the contemporary American political climate / level of dysfunction. But outlawing corruption is not some utopian dream.
The alternative is that paid government officials and government/EU research institutions supply their research results to lawmakers and refuse to read gray papers from corporations or big civil influence groups. That's all well and good as part of the mix, but on its own, a very narrow viewpoint in a complex society. (The fight over who is nominated to these research jobs becomes even more political.)
Removing possibilities of corruption from MEPs means removing their power and moving it into deeper government bureaucracy where it is harder to spot. Now you have non-elected people who work whole their life in government using more power.
