So I came to the objective uselessness of a gardener's services. But I want the backyard to look nice. Things like raised bed planters, which are now sold in various offline and online stores, are easy to use, and I have bought some plants like loaches that grow exactly the way I need them to, without my active participation.
What do you mean lazy? I think it's totally normal to hire someone who does professionally what you've never done in your life. There's this weird mindset I come across a lot "I've never done this before, but I'll just google it, save some money, and do it myself."
I think it all comes down to not wanting to pay for things that seem simple. I've done that too, regretted it many times, ended up paying more, and now if I need something, I'd rather not be that guy who pays twice. And there's stuff like pouring a concrete walkway https://oakshs.ca/concrete/, which I'd never ever do myself. Like it or not, you just have to hire pros.
