This varies by US state. In some states - including New York - it is illegal to prohibit transfer of tickets and therefore illegal to prohibit resale.

Makes sense. What if someone close to you passes away or you get COVID or something and you can't go? That money is just wasted? :/

More fundamentally: once you buy the ticket, it's yours. It should be your decision to resell it if you choose, for any reason. It's a "First sale doctrine" sort of thing in my mind.
