No it isn't. It's more like gig work if anything but often operates in legally gray/illegal areas with less if any chance to unionise. It's harder work than retail, leaves you with less options in your social life, pays barely enough to get by, and is way way more intrusive to the laborer. it's clearly not like other work. If there were no women left in the margins of society with no option, nothing to sell but access to their bodies then the porn industry as we know would die out. It's such an idealistic view to think that a woman chooses to become a sex worker the same way she applies to be a barista or fast food worker.

Also "her own boss" is how libs try to sell the gig economy that leaves the laborers destitute and desperate, be it uber eats or whatever else. Any john/client whatever should be treated with the same scorn as a landlord, a predator preying on less fortunate.
