No, they will never give up. Next step they will be coming to your door demanding you pay them tax on your garage sale transactions, claim you owe them on internet transactions (they are already doing this) and pay up on those girl scout cookies you bought and paid no tax on. I could see them hauling a few people off to jail just to make a point.
Tax Hollywood.
California claimed that if you worked in California for any period of time they were entitled to tax a portion of retirement based on the number of weeks/months/years you lived and worked in California.
Luckily that went nowhere fast because any of the taxes collected would have been more than off set by the costs to establishing and maintain the collection process.
But still it has been seriously discussed a couple of times and I am scared that it isn't dead yet. Why? I was stationed in California from September 1970 to March 1972, TDY for six weeks in 1973, stationed in California from April 1979 through May 1983, plus multiple TDYs from 1985 until 1991. I think the total day count ended up being about 6 years out of 21 years.
