Chill out then, that’s ^^^^ the only real thing that is any worse than tubs/tubes. Once they are holding air there isn’t much for you to do just top up the air every so often like a tub/tube. Every so often depending on your storage conditions you’ll have to remove the valve core and top up the sealant (somewhere between 4 months and a year) but during that time you might have had 3 or 4 race ending p’tures with tubs/tube so in comparison it nothing.
You might want to buy some sort of tyre plug (worm) for a road side repair in the rare event a hole doesn’t seal but your mechanic will probably take care of that rare event too.
