Well an easy counter to your statement, the reason you would need a creeper farm is for netherite, if you need to do all that work, then that means beds are better for a first netherite hunt, and after a little research, I can also tell you that there are more ways to make beds, you have spider spawners, desert temples (these two also have gunpowder but wait) mineshafts and stronghold libraries have webs, piglins give string, and if we really wanna talk villagers, we have shepherds. And once again, you have shulker boxes, and before you complain about needing to go back and forth, first off, don't be lazy, second, it's not that complex, and if shulker boxes are too much, use an ender chest
