The value of IP law for the consumer is in the work itself, which often would not exist but for the ability for its creator to profit from it.
Now as to taxing IP: property (wealth) just is not taxed right now, at least in the US and with the exception of land and/or buildings. There are reasons for and against that, and they pretty much apply to IP, too.
If some state decided to start taxing wealth, IP would be no exemption, although there are a few of specific difficulties with it. IP you created yourself is fiendishly difficult to evaluate, something that is easier if you just bought it, where the market-based price is assumed to be a good proxy for worth.
