The arguments are absolutely not serious. What is an external dwelling of the 6th level, for example?

It seems to me that the arguments are serious.

Taking cans and hives—for me, this is also part of the game and strategy. The ability to take them as early as possible is also a skill.
On which week will Dragon Utopia be taken without cans and hives? Again—it's dragging out the game.
We'll be reading reports like:
"The opponent was given an elf external dwelling" or "on 112 I'm capturing my own secondary, decided not to continue :D "
Such "accidents" will start deciding the game.
Random is random precisely because you play what the computer threw together; that's why we love it! If you want perfect balance—play fixes!

And one more thing. Play about 10 parties with a ban on cans/hives and write down your impressions of the game. I think many will agree (especially those who suggested this before)
