Farming provided the calories necessary for a population that hunting and gathering could not support (so no going back) but required basically working all day to make it work and survive less than ideal conditions. But prior to farming people often had significant more free time.
You can also use "correlated column aliases" (I can't recall the proper name) i.e.
SELECT
id AS foo,
foo || '_1' as foo_n,
right(foo_n, 1) as foo_ordinal
FROM MyTable
WHERE foo = 1;
Again, if this isn't all part of SQL standards, the reality is that a lot of engines have semi-standard (sometimes very proprietary too) ways of handling these now common patterns. For real-world use cases, the standards are unfortunately becoming increasingly irrelevant. I think it would be better in the long term to use standards, but if they can't keep up with actual usage then they will just get ignored.Except this works in most major vendor SQL implementations. And they all support relation aliases in SELECT... Seems the standards have long fell behind actual implementations.

On the first point, just give each person n-1 shards, each missing a different one. Then any 2 can decrypt. Or configure it for however many participants there are and they minimum number needed to encrypt.
