[From many - one.]

In fact a fair number of buglies are considered special treats and are not all that different from eating shrims, crawdads, calmari and the like.

White Oak acorns are sweet, and in North America there are also Beech nuts, black walnuts, butternuts etc..

Generally gatherers spend less time on survival than farmers.

"In fact a fair number of buglies are considered special treats and are not all that different from eating shrims, crawdads, calmari and the like."

Different enough.

"White Oak acorns are sweet..."

Not that sweet.
And only if you cook them, which is hard to do if you're really in a survival situation. Lighting a fire without matches is hard hard hard. Freeze-to-death-before-you-succeed hard.

"Generally gatherers spend less time on survival than farmers"

And less time on Earth too.

As schoolchildren here in California, we were taught about the Costanoan Indians and all the elaborate steps they had to take to render the live oak (a type of black oak, it has the "spiny" leaves) acorns edible. Gather and hull, grind and leach, leach, leach all that nasty tannin away.
