[EM] SODA unfairly hobbles nonparanoid voters.

	0thly, I recommend that you read this article:

> 	Basically, ⸘Ŭalabio‽'s objection is that SODA does not allow non-bullet votes to be delegable. The reason that SODA is designed that way is not "paranoia", as ⸘Ŭalabio‽ claims, but rather simplicity.

	Simplicity is in the eye of the beholder.  What is simple for me is choosing people whom I trust to represent my interests in the Asset-Negotiations and leave them to their work.  If some of them screw me during Asset-Negotiations, I shall never vote for the bad 1s again.  As far as simplicity goes, SODA seems more complex to me than Asset-Voting.

> 	To see why multiple delegable votes would be confusing, consider the following scenario. Let us say that I vote for A and B. After the votes are counted, it turns out that all the other voters voted for X or Y, in a 50/50 proportion. My delegated vote could be decisive. But A approves X, and B approves Y. So both of these approvals are added to my delegated vote, which ends up being useless in deciding between X and Y.

	Either A or B would eventually by won over to the other side by policy-concessions.

> 	Also, making multiply-delegated votes possible would entirely ruin SODA's summability. This would make a number of useful anti-fraud measures impossible, including precinct-level counting, sampled count audits, and voter-auditable cryptographic ballot receipts like those of heliosvoting.org.

	Just make the allowable votes a fixed number.  This is required in 1 form or another in proportional systems.  Indeed, most of the problems with SODA is that it is based on a system designed for creating a proportional legislature, but is modified for both creating proportional legislatures and for single-winner.  These are 2 different domains and should use different systems.  The simplest methods for these domains are:

Single-Winner:
	Approval-Voting

Proportional Legislature:
	Asset-Voting

	SODA should just forget about single-winner.  Because it is based on a proportional-voting system, it is ilsuited for single winner.

	If voters want to make their votes in an Asset-Election nontransferable, that is fine by me, but we should tell them that they run a real risk of disenfranchising themselves.

> 	⸘Ŭalabio‽, I understand and sympathize with your desire for multiple delegation, but I do not see how a SODA-like system could meet that desire without too high a cost in complexity and insecurity. If you think that you can resolve these issues, please propose a specific solution and explore its implications. As you know, voting system design often involves trade-offs, and so "doing P has disadvantage Q" is not a good objection against a system unless it's accompanied by "alternative S avoids Q without causing any other disadvantages as serious".

	My solution is to scrap SODA SODA as being fundamentally flawed and use Approval for single-winner and Asset with 9 votes for proportional with an option to makes the votes nontransferable with the understanding that one _“*PROBABLY*”_ will disenfranchise oneself if one makes the votes nontransferable.

	FairVote started wanting STV for a new house of proportional representation or turning the House of Representatives into an house of proportional representation using STV.  FairVote settled for using STV for single-winner which is IRV.  We all know how lousy IRV turned out.  SODA repeats the mistakes of IRV:

	One tries to use Asset for single winner, but it does not work well, so one modifies it into SODA which instead of working well for single-winner and proportional, works well for neither proportional nor single-winner.

	The fact is that Asset works better than SODA for proportional representation and Approval works better than SODA for single-winner.  SODA just is not a good tool for the job:

	Let is suppose that we tell steelworkers to build a skyscraper using only the tool Allen-Wrench.  The steelworkers are the voters, SODA is the Allen-Wrench, and the pile of rubble which is supposed to be a skyscraper is the legislature.  SODA is good for neither proportional representation nor single-winner.
