I think it's probably still useful to distinguish addictions with hardcore substance related barriers to quitting (think withdrawals) from addictions where the barrier is a lack of dopamine or serotonin or simple habituation.
For people with normal executive function, the second category of problems should be fairly tractable to overcome, whereas the first is still quite difficult.
The second only really becomes an issue when you have a bit of executive dysfunction.
Maybe that distinction is important and one merits the term addiction while the other doesn't? Though both categories seem to be relatively treatable with drugs that massively improve executive function, so the parallels are pretty glaring.
