A paper titled "Three Types of English Pseudo-passives" has these examples (p8):
(31) a. *Seoul was walked around by his father.
b. Seoul can be walked around in a day.
(32) a. *The hotel was stayed in by my sister.
b. The hotel can be stayed in by foreigners.
The paper explains these examples as follows:
Walking around Seoul in a day and staying in the hotel both can characterize the general or characteristic property of Seoul and the hotel. However, if these actions are performed by a particular individual such as his father or sister, they cannot represent the general properties of the subject referent.
I wonder why the writer focuses on the agents in (a) examples being particular individuals. Isn't it the use of modals such as 'can' that allows (b) examples?
For example, aren't these (c) examples possible?
(31) c. Seoul can be walked around by his father.
(32) c. The hotel can be stayed in by my sister.
