Your thinking is that we can't build solar panels and nuclear reactors fast enough, but we can build housing fast enough to move a significant fraction of the population to higher density areas where they don't have to drive as much? Because that's the low-hanging fruit on energy consumption, and it's a massive scale long-term construction project with significant political opposition.
And we should still do it, if only to get housing prices out of crazyland. But what makes you think we can do it any faster than we can build generation capacity?
I guess my point generally is that it is super hard to solve, because it touches everything. But it seems clear that we won't be able to compensate for fossil energy in the needed timeline. For nuclear plants, because it's super slow to build. For solar/wind, well we can't control them (if there is no sun, you get no photovoltaic energy) and we can't properly stock the energy they produce. And in any way, changing everything everywhere to work with electricity instead of fossil fuels is super hard, time consuming, and won't work for everything (oil is used for everything, not just cars).
So yeah, it's super challenging, it requires a lot of work and care everywhere. But the first step is to accept that we can't solve the problem by throwing more technology to it. We need to use technology wisely to get as much energy as we can, but in any case we have to drastically reduce our consumption, and therefore change society.
