Getting rolling stock certified to the tunnel’s stringent requirements will be a challenge. There is no second-hand market (SNCF, who own a majority of Eurostar, have a policy of destroying old trains rather than letting them fall into the hands of competitors), manufacturers of units already certified for the tunnel have long waiting lists, and getting new units certified would take many years.

Sounds to me like wasteful bullshit regulators ought to put a stop to.
That’s really a minor issue compared to all the other challenges. The main one being the secure passport/luggage control the UK requires for any station stops.
