No. I don't see any chance of these clubs "disappearing".
Access to, and control of, a decent venue is certainly helpful, but I don't think it's the be-all and end-all of domestic competitions.
Two court stadiums could certainly house large and profitable domestic competitions, and if clubs had access to an income stream from these comps, they'd be in a better position to negotiate for new courts/stadia. Norwood are in a tougher position, but could quite easily go into partnership with other clubs to get a domestic competition going.
To summarise - a home stadium helps create a link between a domestic comp and a district club, but it's not the only way to get these comps up and running.
At a recent meeting of club Junior Coaching Directors, each club represented gave their support for the domestic competition concept, and most have started discussions to make this happen. If you're not sure of your own club's position, speak to your JCD.
