That's exactly it. I'm "imprisoned" here (sort of- I can easily leave, I just can't easily come back!) but, in normal life, I go to work, I drop my daughter off at nursery, I go to Tesco, I go home, I go to the pub or have a takeaway on a weekend. On a warm day we'll go to Peel and play on the beach and have an ice cream. I'm not off gallivanting every weekend. And so the benefits to my day-to-day life- no social distancing, no masks, music in pubs- far outweigh the disadvantage of not being able to easily leave the island. I had a nice ride out on the Manx Electric Railway this morning. I'd rather have that than an open border and everything shut down, as in the UK.
And in the world of business, Zoom/Teams/Skype/Hangouts have managed to prove that, actually, that face-to-face meeting probably isn't essential after all.
And with all the rules in the rest of Europe, I'd not be rushing off to my usual beach holiday in Ibiza anyway, even if I could.
