hi,
I can't find the vote option that I would choose, so I did not vote. I have been collecting ancient (Roman, Greek, Celt, Byzantine) coins for about 10 years now I never worried about any regulations. Also knowledge is no problem, because there are sources on-line for attribution (Wildwinds, CoinArchives)
As for legal matters, I know a lot of detectorists in the Netherlands that never experience any problem with authorities and are willing to sell finds. Maybe it's different in the UK, but when a find is properly reported to the authorities with photograph and finding place, that's the end of the story. Of course, not all finds are legal, which is always a risk. But.. once a coin is digged up and cleaned, it is impossible to trace.
Most Roman coins that are affordable are Eastern-European finds anyway.

Constantine I (M.Br) RIC VII Thessalonica 101 R2
obv: Constantinus Magnus bust right, CONSTANTINVS AVG
rev: in wreath VOT . XX, DN CONSTANTINI MAX AVG ---- TS gamma IIII
See the mint ? It's TS gamma, Thessalonica. This is not a Western-European find. It cost me 24 euros. I don't worry about forgeries. For prices I can afford, it can hardly be faked. And this is my
best Constantine !
I don't agree with the ugly-issue. How dare you
This is one of my favorites, because I found it myself..

And.. let me show you what
beauty a really affordable Roman coin can have.. delicate portrait of Alexander Severus. Instead of buying this coin I could have chosen to buy a pizza.. did'nt..
