I've experienced this in London about 25-30 years ago. I locked my bike up to a railing outside a block of flats in North London and returned after an hour to find it overlocked with a chain. Spoke to police who said we don't care what you do and that you are entitled to recover your property by any reasonable means, so I hired a pair of bolt croppers and sorted it out. The practical truth (sauce for the goose etc) is that it appears that you can do what you want (not unreasonably or unnecessarily vexatiously) in order to secure access to and enjoy use of your property be it a bicycle or the fence to your property - provided that no other offence is committed, such as obstruction or theft. You could also live and let live for a little while longer, perhaps?
Personally, I don't bother with railings in residential areas these days as people are much more aggressive and disproportionately sensitive about their private side of the private/public boundary...
Hell is other people as someone once said - was it Sartre?
