As a Hawks fan, I could be accused of bias, but I'm not sure of the OP's justification. He/she hasn't stated his/her criteria but it seems to lack any objectivity.
Looking at the list he (from now on I will use "he" in a no=gender specific sense) is looking to retain teams who have gone bankrupt in the last few years. He is looking at giving the Hawks licence to another former franchise who went broke.
We don't have a relegation system like EPL so, just coming last isn't a reason to boot teams. Otherwise, there's a few teams in OP's list who wouldn't be here (Cairns, Adelaide, Sydney, Brisbane).
If it's about financial viability, AFAIK Hawks are still liquid. Maybe not as rich as other teams, don't have a big a budget, but still a solvent business. And despite the small budget and current ladder position, astute observers will see that the Hawks have had several close games and have beaten the league leader. Also, they have made finals and GF several times in the last 10 years. So, they are generally competitive and each year, someone will be last, so that is not a reason to boot teams.
As a long term fan, I would like to see more teams in the league. I actually agree that Canberra should have a team, but not at the expense of the Hawks. They have a strong junior program and several domestic comps, and a decent-sized quite affluent population. I would like Hobart/Tassie to have a team. I can't understand why, as a capital city, they couldn't retain a team. They only need to be as financially viable as the Hawks.
TLDR: there is no rationale to boot the only remaining Foundation club but add a couple more.
