Women are also harassed.
Why don't you ask some of your female friends whether they would want the security when in their apartment buildings?

In that study 1 in 21 men reported being forced to penetrate someone, 4.8%. A further 1.4% of men reported being raped which is defined only as being penetrated, not being forced to penetrate. That's a stupid definition of rape. So it's really more like 6% of men have been raped, which puts the stats at women being about 2x more likely to be raped than men (only 11.5% of women experienced a completed penetration attempt).
Fear is an important thing and we do need to address it, but public policy should be based on factual risks, not irrational fear. Only 7% of rapists are strangers. That means those transients at the AirBnB are the less likely to rape a woman than basically anyone else they know.
And even that includes some murkiness over things like "too drunk to consent".
If you want real rape statistics then look at sexual assault charges, not surveys.
• "Attempted forced penetration," 6.4 percent.
• "Completed alcohol- or drug-facilitated penetration" without the ability to consent, 9.3 percent.
Source CDC referenced in link provided.
1 in 9 completed forced penetration. Another 1 in 15 attempted forced penetration. Almost 1 on 5 for either.
Only 31% of rapes and sexual assaults against women are committed by strangers. [0] An estimated 10% of female murder victims were killed by a stranger. 29% of male murder victims were killed by strangers. [0]
But sure, move the goalposts again. I'm confident you can find a good factoid to support keeping the "wrong sorts of people" (if you know what I mean!) out.
