Alright friend, OP certainly never implied “giving government ubiquitous control over the food supply” by any means, so at least this is clearly a simple case of strawman fallacy.

edit: like if you think about it for literally more than two seconds, you’ll realize that OP’s idea involved building capacity amongst the general population for horticulture, something which fundamentally opposes the idea of giving government ubiquitous control.

Is there a name for the fallacy that something is doomed to fail just because some quasi-communist state tried to implement something similar at some point?

You seem to be assuming that this idea would have to solve all food consumed by everyone. No one is making that assumption except for you.

Only available for children in the summer… I don’t think this isn’t the solution being proposed.

Ah yes, how can we forget that this is Canada’s 200th anniversary, after the signing of the confederation in 1825. Sounds like you’ve definitely got your facts straight…
