However, could a one-time public key receive Monero more than once (as in thousands of times)
Yes, but it is certainly not practical. There are basically two reasons as two why. First, sending Monero to the same one-time public key (stealth address) will be detrimental to unlinkability, i.e., it will create linkability between payments. In addition, sending to the same stealth address is basically similar to a stealth address collision. From Luigi1111's article:
The chance of a collision (two stealth addresses being the same) is cryptographically negligible. Using the Birthday Paradox we can roughly estimate it would take sqrt(l), or about 2^126, stealth addresses being created before having a 50% chance of a collision. The result would be that the colliding addresses become publicly linkable to each other, but not to any others.
Secondly, and this is even worse in my opinion, sending to the same stealth address will "burn" all outputs except one. More specifically, an output is accompanied by a key image (
I = xHp(P)), where
I = the key image,
x = a private key,
Hp = a hash to point function, and
P = one-time public key. As you can see from aforementioned function, sending Monero to the same stealth address will result in multiple key images that are exactly the same. Note that the network will reject a key image if it's already present in the blockchain, because it will be seen as an attempt to double spend. Thus, you will only be able to spend from this stealth address once and the remainder of the outputs will be unspendable.
More practically speaking, let's say you sent 1 XMR twice to
P1 and 2 XMR twice to
P2. Subsequently, you create a transaction that combines
P2 and broadcast it to the network. Now, if you want to create another transaction that again combines
P2, it will be rejected by the network, because the key images are already present in the blockchain and it will be seen as a double spend attempt. Thus, effectively you burned 1+2 = 3 XMR by sending to the same stealth address.
