Edit: just to make sure it's clear - I'm very happy when such skipping happens. A quote from Captive Mind by Czeslaw Milosz:
> When someone is honestly 55% right, that’s very good and there’s no use wrangling. And if someone is 60% right, it’s wonderful, it’s great luck, and let him thank God. But what’s to be said about 75% right? Wise people say this is suspicious. Well, and what about 100% right? Whoever say he’s 100% right is a fanatic, a thug, and the worst kind of rascal.

I see little benefit in developing an alternative system of payment to the dollar, some form of intellectual nudity, implications of which I don't fully understand. The dollar is fine, charge me and leave me alone.
And floats are really a whole other beast than fractions or naturals or real numbers. As I wrote earlier - the "+" operator isn't associative. Python snippet:
def before():
x = 0.0
x += 1.0
for i in xrange(1000):
x += 1e-17
return x
def after():
x = 0.0
for i in xrange(1000):
x += 1e-17
x += 1.0
return x
print before() == 1.0
print after() == 1.0
Will print: True
FalseEdit: for instance, you could imagine a representation (think object of a virtual class in c++) that gives you a fraction and a 1/2^n bound for error, where you can query the number for whatever n you see fit. Still, in some cases it's undecidable to determine which number is greater.
1. For x and y you cannot prove that x<=y or x=>y
2. Every function is continuous
Some hand-waving to see why 1. is a problem: given two numbers, x and y, as a lazily-computed infinite decimal expansion, the program that loops in parallel over the expansions and seeks the first difference (to determine which number is greater) will never terminate if x and y have identical expansions.See this submission from two months ago: https://news.ycombinator.com/item?id=18411935
- my mobile phone
- my landline phone
- all credit cards and bank accounts
- all hosted email solutions
- all other hosted ways of communication (social media, messaging apps)
- all ways of transport unless I own the devices (and even some cars you could own have telemetry these days...)
Basically only talk face to face, ride old cars and use cash or Monero. It's unrealistic.In any case - I agree with you that this seems like a shitty legal pseudo-loophole. At the very least the company you sign mobile contract with needs to share your phone number with those infra subsidies. But then according to GDPR: "15. 1. The data subject shall have the right to (...) access to the personal data and the following information: (...) (c) the recipients or categories of recipient to whom the personal data have been or will be disclosed". Following this rule one should be able to reach the bottom of the data processing chain.
