I don’t see how your post refutes his? Russia is big, but it’s sparsely populated, especially anywhere east of Moscow until you get to Vladivostok. Countries other than Russia in their grid equally if not more so sparsely populated. Top that with disparities in Quality of Life between the two grids, and you find the larger one using less power because it’s services less clients who use less electricity.
Accounting for mining, construction, operation, decommission and disposal, nuclear has less emission that Solar.
The political problems are entirely artificial, fabricated by the fossil fuel competitors and have been soundly disproven.
Nuclear waste is no where near the problem people assume it is. A single plant doesn’t produce more than it can store onsite during it’s entire operation and 100% of all the waste can actually be recycled and ran through newer generation breeder reactors to ‘burn’ the radioactivity and render the resulting ‘waste’ safe as background radiation within a decade or so in a cooling pool. The only reason this isn’t already common practice is nuclear fuel is so abundant it’s not as profitable to do this, It’d be the equivalent of a coal power plant halting using coal for a few weeks so they could shovel in trash from a nearby landfill until it was empty. Less overall power output for less profit.
There is no reason it needs an always on connection for this. Even if there was a camera in the bowl taking pictures of poo (which raises so many privacy questions), the device could easily save hundreds of HD+ quality picture (assuming a toilet camera had that resolution) and send them next time connection is secure.
Always online functionality only makes sense when the function itself is an online task such as a video call or looking up information not saved locally.
Having an always online connection for a toilet suggest it’s gathering much more information passively from your home, using voice activated as a cover to always be listening and thus relaying what it records to server/data center to be filtered through for marketable or exploitable data.
