Most men do not enjoy how hard they're forced to work in 2020. In fact most men would quit their jobs right away if they could take a pill that turns them into a 6'5" Male Model who could circle the globe and fuck whomever he pleases and live off women simping for him. The reason people don't do this shit is because of societal pressure, shame, and the fact that most men can't do it.

Marriage is the bastion for the unattractive man. It gives him (allegedly) guaranteed sex in return for work and emotional companionship. Women don't like it because it restricts them to one man of likely unremarkable genetic status, and men don't like it because the capacity of their genes to spread is truncated by the single woman they get to fuck. If free of consequences, men would take the chance to forego all societal pressures and fuck freely as an international playboy. (much like James Bond, Indiana Jones, or any other male fantasy role in fiction).
