Booking.com has been here for over 20 years and owns no real eastate too. Good morning grandma..
C4S has been here for ages too, chicks can sell their own clips.. Cams ditto... what exactly is new?
No, cams won't replace porn, it requires patience, consistency and good English skills. Most porn chicks want quick money, need to be directed and don't want to spend hours building customer base and enticing annoying dudes to pay for private shows. Once they discover they can be easily captured and then uploaded on tubes they realize it's the same privacy risk as when doing porn shoots, except they don't need to spend hours sitting in front of their computers and get paid in cash when shooting porn.
You can use the same argument for "luxurious" whores that take 100€ per hour, there are many of them here "working" at home, paying no taxes.. yet there are girls who prefer shooting porn, cause they get to work with professionals and they realize that whoring and porn acting are not the same things.
