Much of what you say is true
However
"Ipswich, Southampton, Leicester C, Nottingham F, Stoke, Sunderland, Middlesbrough, Derby, Portsmouth, Coventry, Wolverhampton, Norwich, Swansea, Burnley, Bolton, Blackburn, Wigan. Even bloody Oxford managed three years there! Can anyone add anymore? "
In the case of Nottingham, Stoke, Sunderland, Blackburn, Wigan Leicester etc, those towns are right in the middle of huge areas of football hotbeds. The Lancashire clubs are close neighbours to Liverpool and Manchester, Leeds and Sheffield are 30 miles away. Middlesborough and Sunderland are near enough to Newcastle to be one area. They are all places that have known success. Forest , for instance, have won major European trophies.
So the problem is that geographically Bristol is isolated and so doesn't have the football community of those other areas. In the same way as this is seen as a huge catchment area it is also a hinderance. The one thing that can break that cycle of circumstance is sustained success, in the same way it did for Leeds back in the 60s.
Yes it needs someone to light the firework. It also need someone to deliver more gunpowder too, and it may be that SL has used up his quota.
It needs a lot of gunpowder these days, because foreign investors have arrived and the premium has gone up (e.g check out Leicester's accounts).
