I just don't think that deflation will satisfy Sweft's Law and I believe thst a competing alt 2-3% inflationary cryptocurrency will eventually outcompete bitcoin for the various reasons i have outlined.
The inflation in the economy is cause for Malinvestment, it is a cost industry pays at the expense of efficiency and environment, the net energy in mineral / energy mining and environmental damage and wasted recourses as a result of the inflation caused Malinvestment, will be much higher than the cost of a fixed currency infrastructure through the Hash rate.
To make your argument you will have to prove why the hash rate will scale relative to number of transactions, the to functions do not scale symmetrically, your assumption that they do is the error that makes your argument.
