My only concern with these types of transactions is people avoiding paying taxes on things. Taxes are an important facet of society and many things wouldn't function otherwise.
If people want to trade bitcoin for property, that doesn't seem like a bad arrangement for either party. You claim housing and land prices continuously rise, but that's not true. They may rise over a long period of time but it's never guaranteed. Remember the housing bubble burst in 2008? Housing prices tanked for years after that, we've only now just recovered back to where we were in the past couple years. On top of all that, your area could become worthless as well, such as the rust belt area of the united states. All the manufacturing jobs left the area and now people's property values plummeted because there's limited employment out there, and what employment options there even are are usually just shitty customer service jobs. Housing prices can fall too, in the right circumstances, so don't expect just because you own land or a home that it'll always rise in value, nothing is certain in this world.
