Or it gets there wrong since there is no error correction or detection in the HDMI standard.

Break-up only happens with the MPEG compressed data used for DTT and DSat transmissions. HDMI carries raw un-compressed data. Errors only show up as noise, and can be totally unnoticed by those not looking for them.
It is certainly true though that it is pointless spending a fortune on a cable for a digital interface like HDMI (if the cable works then there is nothing that could be done to make it better). However, spending peanuts may give you a cable that manages to connect but doesn't actually work very well. Though of course you may not even notice and you'll have saved yourself a few quid

Lastly, to Gold - the most misunderstood cable feature. If you gold plate the contacts it doesn't improve the signal but it does stop oxidisation. This will only come into play if you expect the connection to remain in place for years - the connectors will slowly oxidise and cause a loss of signal. Gold works by preventing this oxidisation but only works if both sides, plug and socket are gold plated. With non-gold connectors you may need to clean them every year or two to maintain a good signal but these days who leaves things alone for long enough for this to matter? Gold is used these days just to make it look nice
