You compare New Zealand and Vietnam with the UK. However, the UK has a huge proportion of non-UK citizens who want to be able to visit or be visited by relatives living abroad. Also, a large proportion of the UK population is abroad at any given time. They would be stuck there if there was a zero-covid policy.
The UK is also a leading international hub for air travel, far more so than New Zealand, Australia and Vietnam. Finally, China is finding a zero-covid approach is beginning to fail amid new subvariants.
