I would content that a lot of these long distance projects are 'profitable' of sorts because of the choices made in the respective energy markets. If everybody would simply have the rule of every per X00000 people you build one reactor in a geographic location near them. Then you would simply not need the waste majority of all long and medium distance energy transport. You need some connection to be able to support temporary maintenance but for the most part each region is pretty independent and relatively simply. That reduces your grid complexity a great deal and doesn't require country or even continent wide coordination with lots and lots of highly variable inputs, complex energy price markets and so on.
