The economics of the retail trade are also having a major effect. Rents in High St locations and shopping centres are so high that only shops with huge turnovers can survive in them and model shops are not in that league, they now tend to be in obscure locations hence the hobby is losing it's public profile. Before I retired I was a regular visitor to London on business. In the late 80's there were at least 4 model railway shops in the centre of London and all went in the 90's, there were probably more but they were the handiest for me.
