We can limit immigration very significantly within FOM - we simply chose never to do so.
It allows for the UK to deport people who have failed to find work within three months of arrival, and to deport them for welfare fraud etc - but we never registered immigrants from the EU so we have no idea how long they've been here, so we couldn't do any of that. As EU immigrants cost less/contribute more than UK citizens there was no economic argument for said registration, so it never got done.
The biggest issue here is that the vote for Leave was based on stopping brown people from living here, and in general the inward immigration of brown people is not from the EU, so this is all meaningless from that perspective - but we don't seem to want to confront that, because it would mean confronting the reality that most leavers are racists, to some extent.
