I would ban all recreational travel.
And ban the private ownership of motor vehicles.
Then force everyone to live within cycling/walking distance of where they work.
Also limit all housing to no more than 1 bedroom per person.
If you have more than that, you get assigned a homeless person or refugee to live with you.
This would also apply to National Trust, Royal and Church property.
Don't believe in Global Warming (Karl didn't write about it), but do believe in redistribution of land and wealth.
