The trick is that bigger black holes are less dense. Supermassive black holes can have the density of water. If the universe is gravitationally closed, it would have the density of... well, just look up at night. (Actually much less than that; you see more stars because you're inside a galaxy.)
The density makes the scale recursion less mysterious.
I mean, I simply disagree. The progressive and socialist left's solutions to 'the housing theory of everything' narrative have pretty much failed wherever they have been implemented, especially in the United States.
That doesn't mean I don't think they have any good policies, they certainly do, the issue is that the structure of their policies typically does not have feedback loops that incentivize change when change is needed. There is a reason Stockholm has a 20 year wait list for getting an apartment. With the exception of the Vienna model, which I wholeheartedly support, but that American progressives have all rejected in practice (even if they pretend they don't), every single far-left housing policy system seems to be captured by incumbent electorates, based on seniority, without any willingness to make sacrifices for the next generations.
I hope I made clear from my post that I think these policies come from problems that do not align neatly with political parties, and one of the main reason I see the American political system failing is that incumbent electorates are unwilling to make any sacrifices to help each other.
People don't understand the full impact and consequences of drought.
When you draw down the water table, the ground compacts. You never get that water storage capacity back. There's no way to uncompact hundreds of feet worth of ground across thousands of square miles of earth. There are places in California where the ground has compacted several dozen feet.
When you put poison onto the ground, it usually goes into the ground, and sure, the ground may act like a kind of HPLC column and some of that poison might take years to decades to reach the water table...but then what?
When you melt chunks of the arctic and antarctic, you don't just cause sea water levels to rise. You also reduce salinity, and affect global-scale air and water currents like the jetstream - causing dramatic shifts in temperatures and water content of air.
Indigenous peoples have been warning us for ~10 generations that selfishness will/is destroying the planet. Nobody in power has cared, instead mocking those who do as "snowflakes" and "anti growth" and "anti progress" and so on. All to make more money.
Khan is massively pro-startup and pro-innovation. Her vision of a more decentralized economy is well aligned with the hacker mindset of the Bay Area.
The core of her agenda for antitrust is not about being anti-merger or anti-bigness. Rather, her project is mainly about creating the conditions for pluralistic, bottom-up and more "permissionless" markets. Markets where founders can build successful businesses without necessarily having to rely on large 'gatekeeper' firms as partners. To the extent that large firms are required, Khan's vision is that they shouldn't be able to use their economic power to bargain unfairly or exploitatively with smaller firms.
Part of her agenda is strengthening the merger review process. Merger review is intrinsically hard, because authorities essentially have to try and figure out what the effect will be if the merger is allowed or denied. There is no crystal ball for this, and there are rarely 'right' answers. Yet the merger regime has been very favourable to large firms over the past few decades, and there's a reasonable consensus in the antitrust community that it should be strengthened. A tighter merger process might make startup exits through acquisition less common, but it should also make it easier for startups to grow organically into large companies. In terms of creating a bottom-up and more pluralistic Silicon Valley, that seems like a win to me.
