Maybe, like any system it almost certainly looks better on paper than in practice and I haven't thought about it too hard. Mostly I thought it was an interesting idea.

> They declare a high price they're happy to walk with and then continue trolling people with their patent

They can if they want but by declaring a high price they are also then obligated to pay a lot of taxes. So the system disincentivizes both under and over estimating the value of patents. It also incentivizes property going to the highest value use. So if I can do something more valuable with your patent than you are able to do (for whatever reason) I can afford to pay for it more than you can afford to pay the tax.
