Look around - do you ever see other people doing stuff like this? How's your riding - are you strong enough to ride a up-to-100 kilo bike up the worst grade to your home ? Is your bike up to the task - specifically brakes.
Personally I'd try it, but with a lighter load than pictured, and I'd use a couple more straps. If this feels okay then step up to larger loads. Avoid peak road times cos that's just aggravating others. Also avoid hours of darkness, and consider using DRL lights on the load, or at least brightly coloured markers.
Those straps are trailer or motorcycle tiedowns. You can use anything that is strong enough and tie them off to the trailer so the load cannot move. Check your straps for tightness every few kilometres.
Weather comes into it as well. Avoid towing into a headwind - its best to do this on a still day. Also avoid rain/dampness because even if its not raining, the damp from the road will get on your stuff. And braking co-efficient will not work in your favour if the road is wet.
As for trailer - finding a low one as pictured would be good. The higher off the ground the more unstable on side winds and on corners. My red ex-kids one is only rated to 30 kilos of live-load. The hitch is important too, you don't want to loose the trailer at the wrong moment.
Also, approach stops much slower, lose speed earlier, and brake longer and more gently. I've been jack knifed by my own loaded trailer at a red stoplight as the load lifted my rear wheel and shoved it sideways.
Take corners much slower than normal. I managed to roll this 68 kg loaded trailer on a roundabout, which was embarrassing. Max speed through a corner is 5-10 km/h.
To repeat - you need to have confidence in your bike and especially your brakes. The trailer above easily doubled my stopping distance because of its mass, and also the risk of jack knifing meant I had to slow down the bike slower, over a longer window.
