Lego is still amazing and you don't have to buy expensive sets for your kids to enjoy them. My son loves Legos and if he gets a set for his birthday it doesn't last long before he takes it apart and starts building other stuff with it.

This is one of those instances where it feels like people are terminally online. Or like the meme of the guy standing in the corner while everyone else is having fun at the party. You can find Legos being given away in a local buy-nothing group. It's still just as magical for kids as it ever was. These complaints are only from an adult who doesn't play with Legos. Who cares if sets become collectibles? Get other sets and have fun with Legos. These are toys that are meant to be played with. Play with them.
