Property is never really wholly private or wholly public. Deeds, titles, freeholds, leaseholds, etc all generally come with some form of public obligations to a sovereign. And in a republic the sovereign is a general government which uses its authority on behalf of the people as a whole to maximize their happiness.
> A doctrinaire laissez-faire mentality that is reflexively hostile to all governmental economic intervention
Laissez-faire was originally a progressive ideology advocated by the French physiocrats which opposed the internal tariffs and private privileges which the king, nobility, and church enjoyed under the Ancien Régime. Part of laissez-faire was the idea that governments should collect a large direct tax on landed property and raise 100% of tax revenues from the most privileged classes of society.
These capitalism vs socialism debates are never really worth having.
There's many types of capitalism and really only a subset of what is commonly referred to as capital has a material basis. These debates always oversimplify things, under-estimate the degree to which western economies are central planned by private banks, and ignore the problem of fictitious capital.
