I must be frank and re-state that I've never personally found a problem with EU immigration to the UK, the Roma excepted, but I am quite aware that there are people and communities who have been swamped by strangers. On sites I've known excellent Portuguese mason-paviors, hard grafting Poles, skilled Balts and even an Ace Albanian drainlayer under God knows what passport.
Agriculture and horticulture is utterly dependent on EU migrant labour to get strawberries into our dessert bowls and vegetables to the freezer plant. There have been harvest labour schemes long pre-dating freedom of movement from the new accession states.
None of these would get in under a points system. Nor would young European Erasmus students spending a year in 'intern' type jobs in our hotels and restaurants. Nor would the French Mauritian delivery driver who delivers French goods in London from 'French Click' with care, passion and pleasure.
The UK is a sort of finishing school for bright, sociable, civilised and well-educated young Kermits, Hermans, Italians and Spaniards. The sight of six or eight young Kermits, not one over twenty, taking over a table in a pub for an extended sociable, animated lunch with an assurance, aplomb and maturity utterly alien to our own youths is a learning experience they could charge to watch.
So I'm not going to get exited that we're abandoning a points system. We (or at least I) don't want an end to EU immigration or seasonal workers, just a mechanism to allow us to regulate it where it adversely affects other facets of our national life.
