Looking out onto the garden I see that the Lesser Celandine is off and
running again. I keep trying to get rid of it, but it is an impossible
task.

Does it occur everywhere in the country, or is it trying to tell me
something about my garden conditions?

Yes - that your garden is fairly wet in spring

Does it actually do any harm, will it
smother other plants?

It will compete with things that are around at this time of year but it
dies back fairly early.

or could I just ignore it?

I'd ignore it in shrub borders or anywhere you have biggish plants, and
just try to control it amongst tiny plants.
