yeah I don't know why people still reuse addresses and even using old legacy ones.
if people never re-use an address, won't that mean having to potentially do a shitton of utxo consolidation at some point ?

Those are not related:
-
Every time you receive a payment, you get a new UTXO regardless of the address you gave to receive the payment
-
Every time you pay you could get a new UTXO (your change, if any) regardless of the address you use to receive the change
Re-using addresses does not reduce (or increment) the number of UTXOs

i have to admit, there's always something extra to confuse me about utxos, thanks for explaining though.
so far, my utxo consolidation has been sending to a new address , i only did it once.
as an example, say i i do my monthly dca of 100k sats
over 12 months i have 12 addresses in my ledger that each have 100k sats
my understanding is that i can make a new address, send each of those 12 balances there and i have now consolidated.
is this new recipient address now consolidated, or did i just make ton more utxo addresses?
reply
You don't consolidate addresses, you consolidate UTXOs.
Your assumption is correct, you get 1 new UTXO every month, and at the end of the year you consolidate 12 UTXOs into 1.
The above is true if you use 13 different addresses, the same address for every UTXO or even a mix: it doesn't matter.
This site is excellent explaining Bitcoin:

That is another reason not to reuse addresses.
Also could be a target for the so called "dust attack".

Satoshi's coins are locked to his pubkey (P2PK), not to the pubkey hash, because P2PKH was "invented" later. This means an attacker will first go for Satoshi coins, where he has all the time in the world (instead of 10 minutes) to try to steal the coins.
So, if someday some of the Satoshi's coins move, we should start worrying. Until then is business as usual.
