What is the primary principle behind eminent domain?

The primary principle behind eminent domain is that the government has the right to take private property for public use, provided just compensation is offered to the property owner. This principle is rooted in the belief that the government must have the ability to acquire property to facilitate projects that benefit the broader community, such as building roads, schools, parks, or other infrastructure that serves the public interest.

This process is regulated to ensure that while the government can appropriate property, it must do so in a manner that respects the rights of individuals, including fair compensation. The other options do not accurately reflect the established legal framework or principles regarding eminent domain. For example, taking property for personal gain or controlling all land owned by individuals would be contrary to constitutional protections and individual property rights. Similarly, the notion that property can only be taken with the owner's consent does not align with the purpose of eminent domain, which allows for compulsory acquisition under certain conditions.
