Acquisitions in the sense that they are 'requisites for existence', that which would bind one to future existence. Sure.
As for gold and silver - The note 300 comes at the end of the paragraph 8:
And what may be said to be subject to sickness? Wife and children are subject to sickness, men and women slaves, goats and sheep, fowl and pigs, elephants, cattle, horses and mares are subject to sickness. These acquisitions are subject to sickness, and one who is tied to these things, infatuated with them, and utterly committed to them, being himself subject to sickness, seeks what is also subject to sickness
Gold and silver are not mentioned until paragraph 11 which is on defilement and is, for all intents and purposes, identical with the previous paragraphs. Venerable Bodhi's note then, explains why gold and silver were mentioned here yet not mentioned elsewhere. Gold and silver can be 'defiled' or alloyed with other metals. So, they are in this section and not the others as they are not living beings.
What the Buddha is doing is going through and enumerating all the things that constitute material security, those possessions which denote material wealth, the mundane 'pursuit of happiness' which is the 'ignoble search'. And it is an ignoble search because these possessions are subject to birth, aging, sickness, death, defilement. Also remember, that the Buddha was talking from his own viewpoint of his own search that led to his enlightenment.
“No lists of things to be done. The day providential to itself. The hour. There is no later. This is later. All things of grace and beauty such that one holds them to one's heart have a common provenance in pain. Their birth in grief and ashes.”
- Cormac McCarthy, The Road
Learn this from the waters:
in mountain clefts and chasms,
loud gush the streamlets,
but great rivers flow silently.
