It is true, that it is easier to flee with your wealth if you don't own property, but you are more resilient and less likely to need to flee if you own your own your property, especially if the property is paid off and especially if you are using your property for productive means like gardening, raising animals, business, etc. It also helps if your property is away from the big cities and not in the more oppressive jurisdictions (states, counties, cities)

I'd rather not have to flee, but if things get bad enough, I can still flee and leave my property behind.
