There are a few fundamental flaws with your proposal, but namely the inventor of a patent or holder of IP generally does not just randomly assign a value to their IP and win that amount in the instance of infringement. It's sort of the whole point of proving damages, because it would be impossible to calculate future damages for a violation of IP at the time the IP was created. For example I invent and patent the widget and assign a $1B valuation to the invention. Apple violated my patent, manufactures the widget and sells $100M. Should I sue, my potential damages have nothing to do with the $1B valuation I made up but with the damages I suffered as a result of Apple violating my patent. Alternatively I write a book and slap $1 valuation, because I assume there is no market for my writing or to avoid the big tax until I make it big. JK Rowling Violated my copyright and slaps her name on my book and sells millions of copies, again my damages have zero relation to the valuation I created for the IP.
