comment Availability of a simple limited PRNG algorithm
A PRNG is always repeatable given the same seed, whether or not it is cryptographic. What cryptographic means that if you don't know the seed, the output is indistinguishable from random (even if you are given the rest of the details of how the PRNG works)

comment homomorphic paillier cryptosystem vs Elliptic curve cryptosystem
Do you need the homomorphic properties? If you do, then using a system that gives you those properties would be indicated. If not, then you probably are better off with a crypto system that isn't malleable.

comment Elliptic curve trapdoor function without modular arithmetic?
The other potential issue would be how real-based elliptic curves behave. If (say) the x-coordinate of $dG$ was approximately $c a^d$ for some values $c, d$, this would imply an efficient way to do logs (I almost wrote 'discrete logs'...)

comment Elliptic curve trapdoor function without modular arithmetic?
Real numbers don't work real well in crypto, because we typically hope to be able to express the values we use, and almost all real numbers cannot be expressed, even with an unbounded number of bits.
