The way ISPs operate is nothing short of criminal. Can you imagine if you bought a TV only to find out it could only give you sound or colour for a few hours a day? Or perhaps a car which could only do 15mph between the hours of 4pm-11pm? But hey, the car would be sold as 'up to 100mph!'.

The trouble is is if you do this you will end up with an over engineered network that is prohibitively expensive. If you think about the domestic wiring in your house each socket is capable of upto 13A in isolation, but the ring main circuit is probably only 32A. As engineers we call this diversity, basically you assume an average demand and then provide protection for the network. In the case of domesitc wiring the protection is the circuit fuse or breaker. For the VM network it is the STM policy. You might not like it, but as AFAIK it is essential if the network providers are to provide a commercially viable service.
