alt Hacker NewsIMO, when the last LW transmitter shuts down, the whole band needs to be reallocated to hams. Realistic small-ish antennas are shockingly doable with a capacitance hat, loading coil, and counterpoise.

There’s still a lot of utility stations in the LF/longwave band. Particularly time signals (WWVB in the US, ALS162 in France, DCF77 in Germany, JJY in Japan, etc.) and NDB beacons.
At least in VK/Australia, there’s the 2200 meter band, but it’s quite limited (1W power limit, CW/digital only, 135.7–137.8 kHz).
At the same time, as much as I don’t want the AM broadcast band to die, I’d love an amateur band in the lower/middle part of MF/MW.
"Longwave" has no universally agreed defintion, but good news, amateur radio already has usage of 135.7 kHz to 137.8 kHz.
Building equipment that works on frequencies this low, and avoiding natural interference, can be extremely difficult.
I hate to rain on your parade, but a lot of interests want the low-frequency spectrum. It will absolutely never be allocated to amateur radio.
I thought hams already had plenty of bands. Is there not one in this range?
The witness of the conspiracy practice in me says that the opposite is more likely to happen in the world whose govenments strive to limit its ineterconnectedness and turn it into a set of isolated anclaves not unlike Orwell's Eurasia, Eastasia and Oceania.
The next logical step in that direction would be cracking down on HAM, not liberalization of it.
We'll see.
Best we can do is privatisation and selling it to a party donor.
