Yeah this is what a $60k fine gets you. It’s a silly law to try and prevent metal detecting.
I am deeply fascinated by archeology, but I do think it is insane expecting this of people who do not share my fascination. And the result is likely, most artifacts and sites get lost.
Why? If you make a law, that people get a finders fee if they find something of historic value, only if they stop digging after finding it, but get a fine if they do destroy the site, how would that make more destruction?
Harder is it for homeowners, because real compensation there costs real money - but how else would you compensate people for individual loss, for the common benefit (research)?
