OG the problem is the Leaseholders are often landed gentry families or the Church that have owned the land for centuries. Often, they are unable to sell Freehold for whatever reasons, so produce Leasehold properties. It would be impossible to 'do away' with Leasehold properties. It really is not a big deal to extend leases these days if the landlords are willing. It costs money to extend a lease because the Landlord is giving permission for the Leaseholder to extend the Lease, thus adding significantly to the value of the property. The Landlord does not benefit directly from this up value, so of course wants some form of reward for doing it -usually a percentage of the current market value of the property.
