25Mb doesn't cost any more or less to provide than say 500Mb in reality. If your last mile infrastructure supports those speeds then it supports those speeds. Even the cheapest router possible to buy will do 500Mb.
This comes down to an argument about what "cost", it will cover the marginal cost of an additional subscriber sure (e.g additional customer support, sending a router out, taking a payment each month, 500GB/month across the backbone etc) but will not really be enough to payback the capital cost of the original fibre or coax rollout.

It can once you start adding up all the customers and worrying about 'upstream' connectivity.
One thousand customers at 500Mb can potentially saturate a 400Gb link; one thousand at 25Gb cannot. One has to do capacity planning and average and worst case scenarios to worry about, especially at peak times.
It's only slightly more peaky, and there is no more, or very little additional aggregate bandwidth used. I promise you if you've got 2 x 100G links out of an exchange you will not be able to visually tell from the traffic profile which is 5000 500Mb customers Vs 4000 25Mb customers and 1000 500Mb customers.
