Your questions prompted me to skim through Walter Block's exposition of evictionism [1]. There is a sense of what constitutes a reasonable, gentle, eviction.
"From these examples is derived the principle that when one evicts a
trespasser, or deals with any other violator of rights, one is obliged to do so
in a certain way; it must be done in the least invasive manner possible
consistent with upholding property rights. If a trespasser is on your lawn
and you have a bazooka, you are not entitled to blow him away - not as a first step in any case. That is far too extreme and incompatible with the
doctrine of private property rights. The homeowner has the right to make
sure that the outsider does not trespass further, but he must be evicted in
the gentlest manner possible." -pages 21-22
When there is no possible gentle eviction, due to technological or other circumstantial limitations, Walter Block believes that one can evict even when the sure consequence is death of the tenant.
"Based on the private property rights philosophy, the individual then had the right to evict the trespasser in the most gentle manner possible. If there was no gentle manner feasible, an individual's property rights to her womb transcend the so-called "right to life" of anyone else." -page 22
It looks like the world "gentle" is doing a lot of work here. One could claim, in the spirit of your comment, that a 9 month notice period for eviction is required for gentleness. In an even more bizarre twist, one could argue that an abortion is only gentle when the fetus would be then transferred to a life support system that could bring it to full term. With today's technology, this would imply an earliest date for abortion instead of a deadline. Walter Block does not, in my opinion, clarify the issue of gentleness enough in the document to settle the issue.
I think a major flaw in evictions is the concept of invitation.
You cant invite someone out on a boat ride and then evict them while out at sea in the "most gentle manner feasible". The degree to which conception equates to invitation is certainly debatable, but it is an elephant in the room.
Similarly, if the trespass is allowed for long enough, questions of adverse possession and de facto easements come into play.
