In terms of bums on seats and the maximum cost of seats, I can't see the exisiting number of RL fans being able to support more than semi-pro leagues or fully-pro based on above national average wages rather than 'sports stars wages'

TV money has changed the top end of the game. To be attractive to TV rights money you do need world sports stars playing in top clashes every week. The only way RL could compete here would be for half a dozen clubs to take all the exisiting TV money and pay the worlds top rugby stars. Two top games a week gets more of those TV subscriptions in than a choice of 6 mediocre ones. Sadly mergers don't work in sport so this would be a brutal process. Constant mention of 6 teams in the media may also raise the awareness of the publc to the sport. The talent would be drawn for RL/RU and American Football worldwide so not an easy progression path for British RL players.

For where we are at this point in time, Ealing Trailfinders is more than adequate. However, should we ever return to Super League it will never do.
I have no idea as to how high David Hughes ambitions are. If he really is aiming for promotion then he needs to have a Plan B. For the team to achieve promotion and be denied because our ground is not up to standard, would be awful.

Again it's one of those things that is out of our hands.
Reality is Trailfinders works for us and seems to be reaping rewards, everything in one place, a decent youth team coming through training and playing alongside the senior squad. We seem to be getting back to being a London club rather than a team that plays in londin
The aim has to be get back to Super League but if we do what then re a home?
Can we survive as a full time championship team?

Ealing Trailfinders RU operate on a very similar business model to London Welsh RU i.e. one rich benefactor who is spending his way to the top.
There's talk on an RU site I use that Ealing could well go the way of London Welsh, sooner rather than later, if they are not careful.

Could that mean we become sole tenants in Ealing? Or the major one?

Highly unlikely. Believe it is the Gooley family funding Ealing. Difficult to see them ceasing to fund Ealing and the charity then granting a long lease to another club. Few million quids worth of land there and a charity ready to receive the money if it frees up and planning permission can be granted.

TBH given Michael Gooley is not a young man and Ealing have said they are talking to him about a possible premiership push I'd suggest that there has already been planning for the day he can't put in any more money. The Premiership stuff will be an extension of that planning.

My money is on Ealing playing there for years to come, at what level is the bigger question I suspect.
