In terms of the titled gentleman/vicar/landowner getting on his horse with a team miners to dig three barrows in a day then, no, antiquarianism does not exist.
BUT has the active physical digging aspect been replaced by amateurs (like those on TMA, the stones list etc) who undertake research for the love of it (some of it that does get published but believe me it doesn't cover costs, but hey it's a hobby). Some research is 'blue sky thinking' but it may trigger 'serious' (academic) study.
Can I be the first to coin 'e-antiquarianism'?! The internet is the biggest step forward in antiquarianism since the spade.
