Killing everything and starting over is a drastic approach - one more likely to be found in the regimen of the chemical industry.
Is there any turf at all in your yard? What percentage is grass you'd like to keep? You can get rid of a lot of the stickers by improving the quality of the soil and biologic activity, and depending on what the weeds are, you can spot spray with something like the vinegar and orange oil product Avenger, or use the organic AgriLawn Crabgrass killer to take out crabgrass, chickweed, and more.
Post photos of some patches of the lawn, with enough detail that we can see what the weeds are, and there may be a way to restore the lawn without resorting to a scorched earth approach.
Stickers are often signs that you have poor soil, not much in beneficial organisms and low nutritional value. I would spray a Soil activator on the lawn and spread horticultural molasses down. Bring some life back into your soil and a nicer lawn will follow.

All that's true. Also true is you can try to get rid of all the stickers, but there were some buried back in 1862 that will turn up and sprout if you don't do something. Simply watering and fertilizing will get rid of most of them because something else will grow. Almost all sticker plants are very low growing and require FULL sun. As soon as any canopy of anything grows up taller than the sticker plants, they die away. The seeds remain and may sprout the next time it rains, but they will not take root without the sun.
Scrape everything off the surface, lay some sod, and stickers will not return.
