It's a bit of a sliding doors scenario to argue that one way or the other re: The Force still having players you consider stars. Of that team in 2017 a number have retired (eg. DHP, Lance, Hodge, McCalman etc..), some may have evolved into the players they are now (Hardwick, Philips etc) and been attracted to other teams or opportunities anyway (Coleman, Meaks etc..), so it's hard to say what the shape of the team would be now after COVID and all the other trials Rugby in Australia has gone through. Even some of the players of that time in NRC have moved on and might not be there if still in SuperRugby (Tizzano, McDonald etc).
Did the cutting of the club by the ARU (now RugbyAU) have an impact. No doubt. That said, a higher than club tier of rugby was maintained in WA for those couple of years with NRC & GRR, so their was still a path for local talent. If you are not developing players through the local systems then there is always going to be a challenge in attracting and retaining players who likely have friends and family elsewhere (most likely NSW & QLD). Letting The Force throw more money at it isn't a solution though. WA likely doesn't have the allure of living and playing in Japan, France or Europe in general to some of the young players not wanting to commit to their home states, so there is a whole facet of challenges around selling The Force as a good destination for players which I have no doubt the recruitment team there spend time working on.
Kilbiridge is 28, so unless he has some Australian heritage, the 5 years residency doesn't make him a great option for a possible future Wallabies call up. That said, for The Force, should he want to commit to them in a similar way to Marcel Brache, then that's probably not a bad outcome.
It's a shame that Reesjan Pasitoa has been injured this season as he is a genuine WA lad who looked to have the potential to be a player of note.
