Not sure of you want to continue into the "how" of this kind of lifestyle, but I have a starter suggestion:
First, accept 100% that you don't want to interact with people solely on the
chance that they
might become romantic partners if you work at it. That doesn't mean "avoid people" of course - it means only interact if there's a shared interest, or you're friends, or perhaps it's just someone you bump into.
The point is that you avoid any pressure to do anything other than what you're together for. Which makes interactions much simpler.
You don't have to be responsible for making conversation. You don't have to be entertaining, or clever, or list any personal characteristics that would make you a good life-partner. You don't have to consider being stuck with the bill. You don't pay for the other person's Uber home. You suggest the restaurant
you want, and refuse suggestions that don't appeal to you. Nobody will performatively order a salad, then try to steal your food /lol.
If the other person indicates that they have other expectations (like you paying for things), disengage. Such things are part of the "dark side" of the mating game. But on your (potential) this path, "red flags" are irrelevant to you. They're for avoiding a "relationship downside" which you're immune to.
So if you find there are mismatched wants and needs (such as those expectations), just politely, with zero drama, disengage at a suitable moment.
Simple
I haven't found it drives away good people (though my life situation is probably nothing like yours). But I doubt you'd miss any opportunities to meet truly compatible people.
