I haven't studied the current process, nor whether it has changed recently, but I believe you can still declare a vehicle as being off the road and unusable. You may still be obliged to have some basic insurance for it in place, but that should be cheaper, and you can at least keep it legally, with less expense, until you have removed the parts you need.
It is done through the new system, so there may be a delay, but at least it is free.
On some great and glorious day the plain folks of the land will reach their heart's desire at last, and the White House will be adorned by a downright moron.

Some may not like his views, but what a prediction!
