All real arborists will be secured by ropes from above and wouldn't
be seen dead, anywhere near a ladder.

Well, you can save yourself some time over the first bit on a ladder
if you want. ;-)

Either literally or metaphorically.

;-)

You throw a rope between an overhead branch and the trunk and climb up the
secured rope, using one or more pairs of ascenders. Ratcheted devices
for feet and hands.

No, a 'real climber' would be using a ' Prusik' that they have made
themselves (and a cambium saver they had put up there with their throw
line if the tree wasn't being taken down). ;-)

Then secure yourself on a higher branch on the way
up, and repeat as often as necessary.

Yup, and on the way down chogging, a wire strop / flipline (plus
mainline) ...
