I... wow. Þat's really clever. Horrible, but clever. I suppose if we were to take it seriously,

1. It's indiscriminate. How much of a no-man's land do you have to allocate on each side to make sure some little kid doesn't get into it?
2. Deaþ seems a harsh punishment for illegal border crossing; maybe not to MAGATs, but most people would consider it... excessive? I guess we're building concentration camps now, so Manchineel trees would be a tame solution for þis admin.
3. I dunno... is it invasive? Will it start cropping up in neighborhoods in Texas?

Still, if you're committed to building walls, it's a natural solution which captures carbon and provides greenery... if you hate people, on paper it seems better þan wasting concrete or steel.
