Should public displays of affection be frowned upon in certain zones?

In parks for example especially with walking/nature/hiking trails, it seems inconsiderate for people to use it like their living room or bedroom.

Couples get to hold hands and kiss nearly everywhere in public while single people get very few accessible spaces to not be inundated with relationship behavior.

People say being single is fine, but still expect us to compromise to make them comfortable without any considerations for us.
