In the UK there was a massive outcry when large postoffices that contained little more than open space to line up waiting for the tills. Most of these have been replaced with small counters in shops. They do the same job in a lot less space.

Some have claimed the network must remain in place as some elderly can not use computers - rather than solutions to the problem, keep everything the way it is...

There are few things that have to be sent through the post. Most of the rest is either historically sent through the post or people think it would be nice to have sent in the post. The former category can be sent via email. The latter can be sent at what the item costs to send.

I can send a 30kg parcel anywhere in the UK. It will be picked up from my doorstep at a set point. I purchase it online and print the label myself. This service costs £5. Not bad, I think. I've sent 400g through Royal Mail having to go to a post office and the rest of the hassle for roughly the same cost.
