Why make just a concrete block or barrel?
Cost and complexity / design.
The simple 'barrel o' concrete with a toplink connection and draft link connections can be made for pretty much the price of the concrete for many farm users.
Add in storage boxes, and tool carriers, and implement / trailer hitches starts adding : cost, design complexity and logistics, and more planning.
I made my 'just a concrete barrel' in about a half an hour using 2 wrenches a drill, and a hoe to mix the concrete in the tub. I bolted everything up to the tractor and assembled in place. At the end of half an hour I had hundreds of pounds of cheap ballast, and was washing my tools off. My cost inthe project was the bags of concrete... everything else was misc hardware and surplus items on my farm.
If I want chains to go with me.. they can set in the loader bucket, or on top of the weight.
If I want tools to go with me.. they can set in the loader bucket, on the weight.. or if I need a shovel, it's already been shown that a 2" piece of PVC with a cap on one end, and a few zip ties or a band clamp can add that 'carrier' to a rops or loader support pretty quickly,
As for towing a trailer? well.. that brings up 2 ideas.. 1, If I'm towing a trailer.. do I need the weight box? the trailer is adding some rear weight.. etc. and 2, Depending on design of the 3pt weight, you may still be able to use your swinging drawbar.
With my 3pt weight lifted less than half way, my swinging drawbar bracket on my 660 is free and clear to accept a trailer ball .
Just because some people don't want a 'swiss army knife/gerber/multitool' 3pt weight.. doesn't make a standalone weight a bad idea. There are many implements with a single purpose. That would be like criticizing a 2 bottom plow because it did not have a trailer hitch ball on it, and a tool box, chain carrier, and a place to put your shovel... etc.
