The covid people are the same as the climate emergency people. They have already discussed "climate lockdowns" as a future way to save us all from boiling to death.
Foreign holidays and cruises and the like are going to be reduced over the next decade, which might mean that overseas postage costs will remain high, although they may reduce slightly at first when we're allowed to travel again.
Air travel will be taxed in such as way as to put such holidays out of the reach of nearly everyone, but will be used as an "occasional treat" if a person's social credit score is high enough, like with eating beef.
Some people are now switching to the PoD model for each territory to get around the overseas postage cost issue.
