Entirely depends on your point of view of a "perfect world" and the realism of that. I'd love to just have transporters entirely powered by 100% renewable energy capable to send me anywhere at light speed, but that's not the world we live in.
Does a "perfect world" imply me missing birthdays? Does it imply me missing lunch with close friends? Does it imply me not taking a job outside the local bus line? Does it imply me not visiting a dying relative? If I'm limited to either entirely public transit or a vehicle which can barely do 10 miles at 30mph then yes, I'll miss many of these things.
Covering only 95% cases means you save a lot of money, part of which can be used for those rare events. Does taking a taxi to see a dying relative a couple hundred miles away cost a lot? Sure, but owning a ton of unused capacity for years costs a lot more.
