In the olden days, some parts such as wirewound resistors, wound capacitors, or even vacuum tubes required only mechanical tooling for fabrication (plus vacuum pumps).

It's good that we have a fallback position, lol!  :D

Nothing to do with rocketscience everything to do with owning your own fabs or be in line for some fab to produce your dies. Waiting time at this moment three+ years.

So....  how did they do this in the olden days?  -  to make the simpler parts, is there room for someone to be creative?

Many more companies owned and operated small fabs. But even that wont help you as its not the primary constraint.

Shortage right now, wafers ready to process:

--- Quote from: SUMCO Brief Statement on Consolidated Financial Results for Q1 FY2022 ---the market for 300 mm semiconductor silicon wafers saw demand for both logic and memory applications greatly exceed supply

--- Quote from: SUMCO Brief Statement on Consolidated Financial Results for Q1 FY2022 ---In the market for wafers of 200 mm or smaller, as well, supply and demand remained tight

Consolidation of the supply chains with fewer competitors and high utilization (keeps shareholders happy) made for a fragile market.

It sounds a lot like the baby formula scandal in the US, where it turns out there is a massive dependency on a single manufacturing site....   a situation brought about by lax anti-trust enforcement, among other failings.

Ignoring the demand side for a moment. Did companies like AD shut down fabs to consolidate resources when they acquired LT, and Maxim?

I found this list of semiconductor sites, but it's not clear how up to date it is.

One would think that industry/finanical analysts would know what gets made where, and using what processes, in order to provide  company valuations which are public record.
