In most schematics of ham radio receivers and transmitters the inductor is mostly given specifically as the number of turns around some certain toroidal ferrite ring (for example). This corresponds to a certain inductance, which more often than not is just a standard value, say 220uH. These exist also as "lumped element" components, like the ones in the picture:

It seems a precise inductance is quite difficult to achieve (with homemade coils) and measure, whereas with store-bought inductors this problem is largely gone.

Why are hand-wound inductors so common?

Is it just a nostalgia thing? Do they tolerate more power? Why don't we need to do this with capacitors as well?

Speaking only for myself... I have found air-wound coils to be relatively easy to make and tolerant of misuse. In the several instances I would have preferred to buy an inductor, I found it difficult to find something appropriate.

So --for me-- it is mostly ignorance.

There is also the matter of how much current the device needs to carry. A hand-wound coil made from a few turns of relatively heavy copper (compared to the off-the-shelf devices shown in the question) will pass a lot more current than a tiny pre-bought inductor. The ones in the picture look like 1/4W or so, but you could easily put 5W into a small hand-wound coil with the same inductance.

A hand-wound coil would also have a known (or at least calculated) Q, for which the circuit was designed.
